When evaluating an algebraic expression, the domain is typically all real numbers.
What are real numbers?
Every single number (irrational, rational, natural numbers) except imaginary ones.
When you evaluate an algebraic expression, you can choose from a range of values if it is restricted. If it is not you can only use real numbers.
You can use 1, 50, 1909893, 39309202, and many more. It goes on and on.
And since each number that is being inputted into the expression is different, you may end up with different outputs.

Given: ΔАВС, m∠ACB = 90°
CD
⊥
AB
, m∠ACD = 60°,BC = 6 cm
Find CD, Area of ΔABC
Answer:
CD = 5.196 cm
Area = 31.177 sq. cm.
Step-by-step explanation:
See the attached diagram.
Given that ∠ ACB = 90° in Δ ABC.
Now, CD ⊥ AB and ∠ CDB = ∠ CDA = 90°
Given that ∠ ACD = 60° and BC = 6 cm.
We have to find the length of CD and the area of Δ ABC.
Now, ∠ CAD = 90° - ∠ ACD = 90° - 60° = 30°
Again, ∠ CBD = 90° - ∠ CAD = 90° - 30° = 60°.
Now, from Δ BCD, [tex]\sin 60 = \frac{CD}{BC} = \frac{CD}{6}[/tex]
{Since Δ BCD is a right triangle and ∠ CDB = 90°}
⇒ [tex]CD = 6 \times \sin 60 = 5.196[/tex] cm. (Answer)
Now, from Δ ACD, [tex]\sin 30 = \frac{CD}{AC} = \frac{5.169}{AC}[/tex]
{Since Δ ACD is a right triangle and ∠ ADC = 90°}
⇒ [tex]AC = \frac{5.196}{\sin 30} = 10.392[/tex] cm
So, the area of Δ ABC = [tex]\frac{1}{2} \times BC \times AC = \frac{10.392 \times 6}{2} = 31.177[/tex] sq. cm. (Answer)

What are the roots of the polynomial equation x cubed minus 5 x + 5 = 2 x squared minus 5?
To find the roots of the polynomial equation x^3 - 5x + 5 = 2x^2 - 5, rearrange the equation to equal zero and use methods such as synthetic division or factoring to solve the cubic equation.
Explanation:To find the roots of the polynomial equation x3 - 5x + 5 = 2x2 - 5, we need to set the equation equal to zero and rearrange it:
x3 - 2x2 - 5x + 5 + 5 = 0
x3 - 2x2 - 5x + 10 = 0
Now, we can use various methods to solve this cubic equation, such as synthetic division, factoring, or using a graphing calculator. On finding the roots of the equation, we can determine the values of x.
Ten less than a number is three more than six times the number. Let n represent the number and translate each phase or sentence.
Required number is [tex]\frac{-13}{5}[/tex] and required expression is n – 10 = 6n + 3
Solution:Given that
Ten less than a number is three more than six times the number.
Number is represented by variable "n"
Need to determine equation and the number.
Ten less than number means subtracting 10 from the number
As number is n so ten less than number = n – 10 ------(1)
Six times the number = number multiplied by 6 = 6n
So three more than Six times the number = 6n + 3 --------(2)
As ten less than number is equal to 3 more than six times the number
=> n – 10 = 6n + 3
Solving the above expression for n we get
-10-3 = 6n – n
=> 5n = -13
[tex]\Rightarrow \mathrm{n}=-\frac{13}{5}[/tex]
Hence required number is [tex]-\frac{13}{5}[/tex] and required expression is n – 10 = 6n + 3

Solve algebraically for all values of x:
5x5 + 6x4 + 80x3 + 96x² = 0
Answer:
Submit Answer
Answer:
The values of 'x' are -1.2, 0, 0, [tex]-4i[/tex] or [tex]4i[/tex].
Step-by-step explanation:
Given:
The equation to solve is given as:
[tex]5x^5+6x^4+80x^3+96x^2=0[/tex]
Factoring [tex]x^2[/tex] from all the terms, we get:
[tex]x^2(5x^3+6x^2+80x+96)=0[/tex]
Now, rearranging the terms, we get:
[tex]x^2(5x^3+80x+6x^2+96)=0[/tex]
Now, factoring [tex]5x[/tex] from the first two terms and 6 from the last two terms, we get:
[tex]x^2(5x(x^2+16)+6(x^2+16))=0\\x^2(x^2+16)(5x+6)=0[/tex]
Now, equating each factor to 0 and solving for 'x', we get:
[tex]x^2=0\\x=0\ and\ 0\\\\5x+6=0\\x=\frac{-6}{5}=1.2\\\\x^2+16=0\\x^2=-16\\x=\sqrt{-16}=\pm 4i[/tex]
There are 3 real values and 2 imaginary values. The value of 'x' as 0 is repeated twice.
Therefore, the values of 'x' are -1.2, 0, 0, [tex]-4i[/tex] or [tex]4i[/tex].
In the given triangle, ∠AED ∼ ∠ ABC, AD = 6.9, AE = 7.2, DE = 5.2, and BC = 10.2. Find the measure of BD and CE. Round your answer to the nearest tenth.
Answer:
The measure of side BD is 8.6 and The measure of side CE is 8.4
Step-by-step explanation:
Given as :
The Triangle is ABC with side AB , BC , CA
And The points E and D is on the side AB and AC
So, AED is a Triangle
And Δ AED [tex]\sim[/tex] Δ ABC
The measure of side AD = 6.9
The measure of side AE = 7.2
The measure of side ED = 5.2
The measure of side BC = 10.2
Let The The measure of side EB = x
And The measure of side DC = y
So, From similarity property
[tex]\dfrac{AB}{AE}[/tex] = [tex]\dfrac{AC}{AD}[/tex] = [tex]\dfrac{BC}{ED}[/tex]
Or, [tex]\dfrac{AB}{AE}[/tex] = [tex]\dfrac{BC}{ED}[/tex]
So, [tex]\dfrac{7.2 + x}{7.2}[/tex] = [tex]\dfrac{10.2}{5.2}[/tex]
Or, 5.2 × ( 7.2 + x ) = 10.2 × 7.2
Or, 37.44 + 5.2 x = 73.44
Or, 73.44 - 37.44 = 5.2 x
∴ x = [tex]\frac{36}{5.2}[/tex]
I.e x = 6.9
Now in Δ BED
BE² + ED² = BD²
Or, 6.9² + 5.2² = BD²
Or, BD² = 74.65
∴ BD = [tex]\sqrt{74.65}[/tex]
I.e BD = 8.64
Or, BD = 8.6
Similarly for y
[tex]\dfrac{AC}{AD}[/tex] = [tex]\dfrac{BC}{ED}[/tex]
Or, [tex]\dfrac{6.9+y}{6.9}[/tex] = [tex]\dfrac{10.2}{5.2}[/tex]
Or, 5.2 × ( 6.9 + y ) = 10.2 × 6.9
Or, 35.88 + 5.2 y = 70.38
or, 5.2 y = 70.8 - 35.88
Or, 5.2 y = 34.5
∴ y = [tex]\frac{34.5}{5.2}[/tex]
I.e y = 6.6
Now in Δ CED
CD² + ED² = CE²
Or, 6.6² + 5.2² = CE²
Or, CE² = 70.6
∴ CE = [tex]\sqrt{70.6}[/tex]
I.e CE = 8.40
Or, CE = 8.4
Hence The measure of side BD is 8.6 and The measure of side CE is 8.4 Answer
Answer:
By using geometric calculations,the measure of BD and CE are 6.9 and 7.4 respectively.

Using some synthetic division, we have
3 [ 1 - 4 -3 18 ]
3 -3 -18
_______________
1 -1 -6 0
The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)
So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0

Abc bookstore sells new books, n, for $12, used books, u, for $8, and magazines, m, for $5 each. The store earned $340 revenue last month. The store sold 5 more used books than new books, and twice as many magazines as new books. Using substitution method, how many magazines, new books, and old books did ABC bookstore sell?
Answer:
The number of new books sold = 10
The number of used books sold (u) = 15
The number of magazines sold (m) = 20
Step-by-step explanation:
Let us assume the number of new books = n
So, the number of used books sold (u) = New books sold + 5 = n + 5
Also, the number of magazines sold (m) = 2 x ( Number of new books sold)
= 2 n
⇒ u = n + 5, m = 2 n
Here, the cost of each new book n- = $12
So, the cost of n new books = n x ($12) = 12 n
the cost of each used book u = $8
So, the cost of u = (n+ 5) used books = n+5 x ($8) = 8 n + 40
the cost of each magazine m = $5
So, the cost of m = (2n ) magazines = 2n x ($5) = 10 n
Also, total earnings = $340
⇒ 12 n + 8n +40 + 10 n = 340
or, 30 n = 300
or,n = 300/30 = 10
Hence the number of new books sold = n = 10
The number of used books sold (u) = n + 5 = 15
The number of magazines sold = m = 2 n = 20

here is an equation that is true for all values of x:5(x+2)=5x+10. Elena saw this equation and says she can tell 20(x+2)=4(5x+10)+31 is also true for any value of x. How can she tell? Explain your reasoning.
Elena is wrong, because the two sides of equation are not equal for all values of x
Step-by-step explanation:
An equation of x is true for all values of x when the left hand side
is equal to the right hand side
To prove that an equation is true for all values of x do that
Simplify the left hand side and the right hand sideSolve the equation to find x, you will find the x in the left hand side is equal to x in the right hand side, so they canceled each other, and the numerical terms in the two sides equal each other, that means the equation is true for any values of xLets check that with given equation 5(x + 2) = 5x + 10
∵ 5(x + 2) = 5x + 10
- Simplify the left hand side
∵ 5(x) + 5(2) = 5x + 10
∴ 5x + 10 = 5x + 10
- Subtract 5x from both sides
∴ 10 = 10
∵ L.H.S = R.H.S
∴ The equation is true for all values of x
Lets do that with Elena's equation
∵ 20(x + 2) = 4(5x + 10) + 31
- Simplify the two sides of the equation
∵ 20(x) + 20(2) = 4(5x) + 4(10) + 31
∴ 20x + 40 = 20x + 40 + 31
- Add like terms in the right hand side
∴ 20x + 40 = 20x + 71
- Subtract 20x from both sides
∴ 40 = 71 ⇒ and that not true
∵ L.H.S ≠ R.H.S
∴ The equation is not true for all values of x
Elena is wrong, because the two sides of equation are not equal for all values of x

what is the measure of the vertex angle of an isosceles triangle i’d one of its base angles measures 42°
The measure of the vertex angle of the isosceles Δ is 96°
Step-by-step explanation:
In the isosceles triangle
Two sides are equal in lengthsThe angle between the two equal sides is called vertex angleThe other two angles are called base anglesThe base angles are equal in measure∵ The measure of one of the base angles of an isosceles Δ = 42°
- The base angles are equal in measure
∴ The measure of the other base angle = 42°
∵ The sum of the measures of the interior angles of any Δ = 180°
∴ 42 + 42 + measure of the vertex angle = 180
∴ 84 + measure of the vertex angle = 180
- Subtract 84 from both sides
∴ measure of the vertex angle = 96°
The measure of the vertex angle of the isosceles Δ is 96°

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Final answer:
Jason will have to work approximately 6.67 weeks, or about 6 weeks and 5 days, to pay off a $1200 mistake if he earns $4.50 per hour after government income reduction.
Explanation:
To calculate how many weeks a student would have to work to pay for a $1200 mistake, we will use the information provided about Jason's income and work scenario as a reference. According to the information, Jason nets $4.50 for every hour of work due to a reduction in government income. Thus, if Jason has to repay $1200, we will divide this amount by his net hourly income to find the total hours he needs to work.
$1200 ÷ $4.50 per hour = 266.67 hours
Now, to convert these hours into weeks, we assume a standard work week is 40 hours. Therefore, we divide the total hours by 40 hours per week.
266.67 hours ÷ 40 hours per week = 6.67 weeks
Jason will have to work approximately 6.67 weeks to pay off a $1200 mistake.

9c + 90 < -27
9c + 90 - 90 < -27 - 90 .... see note 1
9c < -117
9c/9 < -117/9 ... see note 2
c < -13
-----------
note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side
note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will not flip as we are dividing both sides by a positive number.
JobFind charges employers x dollars to post a job on their website. They offer a 16%
discount if 20 or more jobs are posted. If 31 jobs are posted by a specific employer,
express the discount as a percent.
Answer:
[tex](31x)\times 16\%[/tex]
Step-by-step explanation:
Given: Discount offered is 16% on 20 or more job posting.
x dollars is charged on every job posting on website.
Now, lets find the discount on 31 job posting.
∴ Total cost on 31 job posting = [tex]\textrm{charges for one job posting}\times \textrm{Total number of job posting}[/tex]
⇒ Total cost on 31 job posting= [tex]x\times 31= \$ 31x[/tex]
As we know 16% discount been offered for 20 or more job posting
∴ Discount offered on 31 job posting = [tex]31x\times 16\%[/tex]
Discount offered by JobFind to the employer is [tex](31x)\times 16\%[/tex]
Final answer:
The discount percentage for posting 31 jobs on JobFind is 16%, which remains constant as it meets the criteria of posting 20 or more jobs.
Explanation:
To express the discount as a percent for an employer posting 31 jobs on JobFind, we need to calculate the percentage reduction based on the original price. Since 31 jobs qualify for a 16% discount, the calculation is straightforward.
Given:
The original discount offered is 16% for 20 or more jobs.
The number of jobs being posted is 31, which exceeds the 20 job threshold.
Hence, the discount percentage for 31 jobs remains the same as the original discount percentage, which is: 16%.
No further calculations are necessary because the question simply asks to express the given discount, not to calculate the total discounted amount or savings.
