Answer:

x² + 2x - 3

Step-by-step explanation:

Given

(x + 3)(x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 1) + 3(x - 1) ← distribute both parenthesis

x² - x + 3x - 3 ← collect like terms

= x² + 2x - 3

Answer:

x^2+2x−3

Step-by-step explanation:

lets use the multiplication property of distrubution.

x * x = x^2

x * -1 = -x

(x+3)(x−1)

=(x+3)(x+−1)

=(x)(x)+(x)(−1)+(3)(x)+(3)(−1)

=x2−x+3x−3

=x^2+2x−3

Answer:

The arc measure of BC is 64

Step-by-step explanation:

1. Calculate the full circumference of the circle

C=2pir

=2pi(18)

=36pi

2. Figure out the arc measure

arc length/circumference=arc measure/degrees in a circle

14pi/36pi=arc measure/360 (solve for arc measure)

14pi/36pi *360=140

The measures of BC and CA add up to the measure of BA

mBC +76=140

BC=64

To draw the image of a quadrilateral under a translation, shift every point of the quadrilateral accordingly. The translated points form the new quadrilateral.

To draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down, you need to shift every point of the quadrilateral 2 units to the right and 5 units downwards. For example, if point A was at (2,3), its new point after the translation would be at (2+2, 3-5) = (4,-2). You will need to do the same for points B, C, and D. Once you have the new coordinates for A, B, C, and D, simply connect them in the same order to get your translated quadrilateral. Remember that the shape and size of the quadrilateral will not change during the translation, only its position on the graph.

It's thirty because median is the middle of all numbers, and thirty is the middle of all numbers.

Answer:

Option B.

Step-by-step explanation:

It is given that,

Number of $1 bills = 5

Number of $5 bills = 4

Number of $10 bills = 6

Number of $20 bills = 3

So,

Total number of bills = 5 + 4 + 6 + 3 = 18

We need to find the probability of a 1 then a ten (without replacement).

Probability of selecting $1 bill in first draw [tex]=\dfrac{5}{18}[/tex]

After one draw, the number of remaining bills is 18 - 1 = 17.

Probability of selecting $10 bill in second draw [tex]=\dfrac{6}{17}[/tex]

The probability of a 1 then a ten is

[tex]P=\dfrac{5}{18}\times \dfrac{6}{17}=\dfrac{5}{51}[/tex]

Therefore, the correct option is B.

Measure of E is congruent to K, so E is 50 degrees.

Measure of G is congruent to L, so G is 105 degrees.

Measure of F is congruent to J, J is 180 deg - 50 deg - 105 deg = 25 degrees, so F is 25 degrees.

Answer:

It is C. If a2 + b2 =c2, then the triangle is a right triangle.

Step-by-step explanation:

If a triangle has side lengths a, b, and c, where c is the longest side, then the statement "If a2 + b2 = c2, then the triangle is a right triangle", the correct option is C.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

We are given that;

Sides of triangle are a, b and c

Now,

This statement is known as the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs (a and b) is equal to the square of the length of the hypotenuse (c).

Conversely, if a triangle satisfies the Pythagorean Theorem, then it is a right triangle.

Therefore, by Pythagoras theorem the answer will be a2 + b2 = c2, then the triangle is a right triangle.

Solution:

surface area of a piece of paper = 137 sq cm

Use the fact that 10 mm = 1 cm to convert this area to mm^2

[tex]1\ cm = 10\ mm[/tex]

Then,

[tex]1\ cm^2 = 100\ mm^2[/tex]

Convert  137 sq cm to sq mm

[tex]137\ cm^2 = 137 \times 100\ mm^2\\\\137\ cm^2 = 13700\ mm^2[/tex]

Thus, surface area of a piece of paper is [tex]13700\ mm^2[/tex]

To convert the surface area of a piece of paper from cm² to mm², use the conversion factor 1 cm² = 100 mm².

To convert the surface area of a piece of paper from square centimeters (cm²) to square millimeters (mm²), we can use the conversion factor that 10 mm = 1 cm. Since we are given the surface area as 137 cm², we can multiply it by the conversion factor to get the value in mm².

Conversion factor: 1 cm² = (10 mm)² = 100 mm²

Therefore, the surface area of the paper in mm² is 137 cm² x 100 mm²/cm² = 13700 mm².

Answer:

A = 200.96 units^2

Step-by-step explanation:

We know the circumference is given by

C = 2 * pi *r

Approximating pi by 3.14

50.24 = 2 * 3.14 *r

50.24 = 6.28 r

Divide each side by 6.28

50.24/ 6.28 = 6.28r/6.28

8 =r

Now we can find the area

A = pi * r^2

A = 3.14 * r^2

A = 3.14 (8)^2

A = 200.96 units^2

Answer: x=6

Y=6

Step-by-step explanation:

Using the elimination method

3x+5y=48.....equ1

-3x+5y=12......equ2

Add equation 1 &2

3x+5y=48

+

-3x+5y=12

Answer =

10y=60

Y=60/10

Y=6

Substitute for y in equation 1

3x+5y=48

3x+5(6)=48

3x+30=48

3x=48-30

3x=18

X=18/3

X=6

Therefore,

X= 6

Y= 6

Answer: x=6

Step-by-step explanation:

Let's solve your system of equations by elimination.

3x+5y=48;−3x+5y=12

Steps:

3x+5y=48

−3x+5y=12

Add these equations to eliminate x:

10y=60

Then solve

10y=60

for y:

10y/10=60/10

(Divide both sides by 10)

y=6

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

3x+5y=48

Substitute

6 for y in 3x+5y=48:3x+(5)(6)=48

3x+30=48

(Simplify both sides of the equation)

3x+30+−30=48+−30

(Add -30 to both sides)

3x=18

3x/3=18/3

(Divide both sides by 3)

x=6

Answer:

A, D, and G

Step-by-step explanation:

Let's try each of the answer choices, one by one.

A) Plug x = 2 into each expression and see what we get.

7x + 4 = 7 * 2 + 4 = 14 + 4 = 18

3x + 5 + 4x - 1 = 3 * 2 + 5 + 4 * 2 - 1 = 6 + 5 + 8 - 1 = 18

Since they're both 18 when x = 2, A is true.

B) The statement says that the expressions are only equal for x = 4 and x = 8, but as we saw from A, they're also equal when x = 2, so B is wrong.

C) Let's try to find a counterexample for this by plugging in an odd number into each expression, like 1:

7x + 4 = 7 * 1 + 4 = 7 + 4 = 11

3x + 5 + 4x - 1 = 3 * 1 + 5 + 4 * 1 - 1 = 3 + 5 + 4 - 1 = 11

We see that these two expressions are equivalent when x = 1, which is an odd number, so this contradicts the statement that they're only equal when x is even. C is wrong.

D) Let's combine like terms for the expression 3x + 5 + 4x - 1:

3x + 4x + 5 - 1 = 7x + 4

Notice that this is the exact same expression as the first one, which is 7x + 4 so that means for any x, these two expressions will always be the same. D is thus true.

E) This is not true because it's possible that two expressions aren't equivalent but have the same value for a certain odd number and a certain even number. E is incorrect.

F) Obviously, if the two expressions are equivalent, they will give the same answer for any input of x, including when x = 0, so F is wrong.

G) Again, the two expressions will always be equal, including when x = 8, so this statement is true.

The answers are A, D, and G.

Answer: measure angle 2 is 72

Step-by-step explanation: All angles of a triangle add up to 180 so you add 42 and 30 to find measure angle 1 which would be 108 now a horizontal line is 180 is you subtract 108 from 180 and you get 72.

So the answer is of option D.

The price of one drink is $7.5

The price of one bag of popcorn is $9.25

Step-by-step explanation:

Let us assume,

Emily spends a total of $78.50 on 2 bags of popcorn and 8 drinks.

⇒ 2x + 8y = 78.5  -------(1)

Lydia spends a total of $89.50 on 4 bags of popcorn and 7 drinks.

⇒ 4x + 7y = 89.5  --------(2)

To solve for x and y values :

Multiply eq (1) by 2 and subtract eq (2) from eq (1),

  4x + 16y = 157

- (4x + 7y = 89.5)

        9y = 67.5

⇒ y = 67.5/9

⇒ y = 7.5

∴ The price of one drink is $7.5

Substitute y = 7.5 in eq (1),

⇒ 2x + 8(7.5) = 78.5

⇒ 2x + 60 = 78.5

⇒ 2x = 78.5 - 60

⇒ 2x = 18.5

⇒ x = 18.5/2

⇒ x = 9.25

∴ The price of one bag of popcorn is $9.25
