the square of a number and 7 times a number are -10
Write the equation and the answer
Step-by-step explanation:
The sum of the square of a number and 7 times a number
The phrase a number means an arbitrary variable, let's call it x.
x
Square the number:
x^2
7 times the number means we multiply x by 7:
7x
The sum means we add x^2 and 7x
x^2 + 7x
Answer:
The answer is x² + 7x + 10 = 0.
Step-by-step explanation:
First, you have to make an expression. By reading the question, we can make it :
Let number = x,
Square of a no,
x²
7 times a no,
7 × x
= 7x
And means ADD equals to -10,
x² + 7x = -10
x² + 7x + 10 = 0
(By forming an equation, you have to let expressions equals to 0, so I add 10 to both sides in order to get rid of -10)

determine the zeros & the y-intercept of the function 3(x-3)(x-2)
Answer:
see explanation
Step-by-step explanation:
Given
y = 3(x - 3)(x - 2)
To find the x- intercepts, let y = 0, that is
3(x - 3)(x - 2) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are x = 2 and x = 3
To find the y- intercept let x = 0 and equate for y, that is
y = 3(0 - 3)(0 - 2) = 3(- 3)(- 2) = 3 × 6 = 18
Thus the y- intercept is y = 18

Kareem drove 225 miles using 10 gallons of gas. At this rate, how many gallons of gas would he need to drive 441 miles?
how many gallons
Answer:
19.6 gallons
Step-by-step explanation:
If 10 gallons of gas were used to drive 225 miles then If kareem drove on 1 gallon of gas would take 22.5 miles.
so 1 gallon=22.5 miles,441 miles=19.6 gallons because,441/22.5=19.6 gallons.
The Kareem 19.56 gallons of gas to drive 441 miles at the same rate.
To find the number of gallons Kareem to drive 441 miles at the same rate, set up a proportion based on the given information:
Miles driven / Gallons of gas = Miles to be driven / Gallons of gas
Using the values provided:
225 miles / 10 gallons = 441 miles / x gallons
cross-multiply to solve for x:
225x = 10 ×441
Dividing both sides of the equation by 225:
x = (10 ×441) / 225
Calculating the value:
x ≈ 19.56

What is the area of this composite figure?
Answer: 978 in. squared
Step-by-step explanation:
area of the rectangle : 24 x 30 = 720
area of the two triangles combined : (9 x 12) ÷ 2 = 54 x 2 = 108
area of the triangle on top of the other triangle : (20 x 15) ÷ 2 = 150
720 + 108 +150 = 978
A gardener has a circular garden, which he divides into four quadrants. He has four different kinds of flowers, and he wants to assign a flower to each quadrant, so that adjacent quadrants are not planted with the same kind of flower. (Also, the gardener can use the same flower more than once.) How many different gardens are possible?
Answer:
84Explanation:
Call the quadrants I, II, III, and IV, counterclockwise, and the kinds of flowers A, B, C, and D.
Start by assigning a flower of kind A to quadrant I.
Then, quadrant II can have flower B, C, or D.
If it is B, then quadrant III can have either A, C, or D. If it isIf quadrant III has A, then quadrant IV can have either B, C, or D. That is 3 different gardens.
If quadrant III has C, then quadrant IV can have either B or D. That is 2 different gardens.
If quadrant III has D, then quadrant IV can either either B or C. That is 2 different gardens.
Those are all the possible different gardens if A is assigned to quadrant I and B is assigned to quadrant II: 3 + 2 + 2 = 7.
Working yet with A in quadrant I but assigning C to quadrant II, you can make the same reasoning as above to get other 7 gardens.
The same with A in quadrant I but D in quadrant II, other 7 different gardents.
In total, you find 7 × 3 = 21 different gardens when flowers of kind A are assingned to quadrant I.
Starting with a flower of kind B in quadrant I, there will be other 21 different gardens. The same for C and D. Then, in total, there are 4 × 21 = 84 different possible gardens.
Answer:
84
Step-by-step explanation:
Quadrants A and C either have the same kind of flower, or they have different flowers.
If quadrants A and C have the same kind of flower, there are 4 ways to choose this flower. There are then 3 ways to choose the flower for quadrant B, and 3 ways to choose the flower for quadrant D, so there are 4 x 3 x 3 = 36 possible ways in this case.
If quadrants A and C have different kinds of flowers, then there are 4 ways to choose the flower for quadrant A, then 3 ways to choose the flower for quadrant C. Then there are 2 ways to choose the flower for quadrant B, and 2 ways to choose the flower for quadrant D, so there are 4 x 3 x 2 x 2 = 48 possible ways in this case.
Therefore, there are a total of 36 + 48 = 84 ways to plant the flowers.
5. Celia gets paid biweekly. Her biweekly salary is $1,763.28. What is her annual
salary?
Answer:
Her annual salary is $45,845.28
Step-by-step explanation:
Multiplication is the process of multiplying. Celia' s annual salary is $48,845.28.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that Celia's biweekly salary is $1,763.28. Therefore, her weekly salary will be,
Celia's weekly salary = Celia's biweekly salary/ Number of weeks
Biweekly mean once in two weeks, therefore,
Celia's weekly salary = $1,763.28 / 2 weeks
Celia's weekly salary = $881.64 per week
Now, a complete year has 52 weeks, therefore, Celia's annual salary will be,
Celia's annual salary = Celia's weekly salary × Number of weeks in a year
= $881.64 per week × 52 weeks
= $48,845.28
Hence, Celia' s annual salary is $48,845.28.

1) Determine the GCF and
2) write the expression in factored form.
(6x2 + 4x) + (4x2 – 8x)
Hey there,
The first step in solving this problem would have to be to add the two binomials together:
10x² - 4xKnowing this now we find the GCF which would have to be 2x which goes into both terms.
The factored form would have to be 2x(5x - 2).
The GCF is 2x and the factored form is 2x(5x - 2).
Hope I helped,
Amna
The GCF for the expression (6x2 + 4x) + (4x2 - 8x) is 2x, and the expression in factored form is 2x(5x - 2).
To determine the greatest common factor (GCF) and write the expression in factored form for (6x2 + 4x) + (4x2 - 8x), we should first combine like terms:
6x2 + 4x + 4x2 - 8x = 10x2 - 4x
We can then identify that both terms have a common factor of 2x. Factoring that out, we get:
2x(5x2/2x - 4/2) = 2x(5x - 2).
how do you factorise 18x² + 9x?
please show the steps an answer fully, please
Answer:
9x(2x + 1)
Step-by-step explanation:
Looking at the two terms, notice that you can write the first term as:
18x² = 9x * 2x
Then, we can see that the first term and second term both have 9x in them. That means 9x is a common factor, so we can take it out from both of them ("take it out" basically means "divide"):
18x² + 9x = 9x * 2x + 9x = 9x * (2x + 1)
Thus, the factored form is 9x(2x + 1).

Find the exact length of the third side.
Answer:
The third side is sqrt(5)
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
We know the legs are 1 and 2 and we are looking for the hypotenuse.
1^2+2^2 = c^2
1+4 = c^2
5 =c^2
Take the square root of each side
sqrt(5) = sqrt(c^2)
sqrt(5) =c
The third side is sqrt(5)

A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that the angle of elevation to the top of the mountain is 31. From a point 1000 feet closer to the mountain along the plain, they find that the angle of elevation is 34. How high (in feet) is the mountain?
Answer:
5507.79 feet
Step-by-step explanation:
To find the height of the mountain, we can draw triangles as in the image attached.
Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.
Then, we can use the tangent relation of the angles:
tan(34) = h/x
tan(31) = h/(x+1000)
tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:
h/x = 0.6745 -> x = h/0.6745
using this value of x in the second equation:
h/(x+1000) = 0.6009
h/(h/0.6745 + 1000) = 0.6009
h = 0.6009 * (h/0.6745 + 1000)
h = 0.8909*h + 600.9
0.1091h = 600.9
h = 600.9 / 0.1091 = 5507.79 feet

Which function is the inverse of f(x) = 2x + 3?
Answer:
y = 1/2x - 3/2
Step-by-step explanation:
The easiest way to find the inverse is to switch x and y and solve for y.
y = 2x + 3
x = 2y + 3 (Switch)
x-3 = 2y (Subtract y from both sides)
x/2 - 3/2 = y (Divide both sides by 2)
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
y = 2x+3
To find the inverse, exchange x and y
x = 2y+3
Solve for y
Subtract 3 from each side
x-3 = 2y+3-3
x-3 =2y
Divide each side by 2
x/2 -3/2 = 2y/2
1/2x -3/2 =y
The inverse is 1/2x -3/2

1
Step-by-step explanation:
because on how you show for 2 when you want to win have an accurate meaning of an number
Answer: Either spinner
Step-by-step explanation: I hope this makes sense, as I had the same question :)
I would choose either spinner because there is an equally likely probability to land on a greater number using either one. If you join the same numbers together on spinner 1 (all the 1's together, 2's together, and 3's together), the section they would make would be the same size as that same number section on spinner 2.
OR (more detailed one)-
The probability of landing on a number greater than your friend on either spinner is equally likely. 1 and 2 on the first spinner are both 3/8 of the spinner and 3 is 2/8 which is the same ratios as the second spinner. The difference is that on spinner #1, the numbers are split up and spread out from each other (ex. 1,2,3,2,3,1), and in spinner #2 all the 1's, 2's, and 3's are together to make bigger looking chunks. The area of each number is the same on both spinners.

Write the fractional notation in lowest terms.
110 minutes to 4 hours.
Final answer:
To convert 110 minutes to a fraction of 4 hours, we first turn both quantities into minutes and then form a fraction. Reducing this fraction to its lowest terms, 110 minutes to 4 hours can be expressed as the fraction 11/24.
Explanation:
To express 110 minutes in terms of hours, we need to divide the number of minutes by 60, since there are 60 minutes in an hour.
110 minutes ÷ 60 minutes = 1 hour 50 minutes
Now we have to represent 1 hour 50 minutes as a fraction of 4 hours. First, let’s convert 1 hour 50 minutes entirely to minutes to make it easier to compare. There are 60 minutes in an hour, hence:
1 hour = 60 minutes
50 minutes = 50 minutes
Total minutes = 60 + 50 = 110 minutes
Since we know 4 hours is the same as 240 minutes (4 hours x 60 minutes/hour), we can now write the fractional notation:
110 minutes / 240 minutes
Reducing this fraction to lowest terms by dividing both the numerator and the denominator by 10 yields:
11 / 24
Therefore, 110 minutes to 4 hours is expressed as the fraction 11/24 in lowest terms.
