Answer:option A is the correct answer

Step-by-step explanation:

The given expression is

4( x + 5) + 4x + 8

To simplify the given expression, the first step is to open the parenthesis by multiplying each term in the parenthesis by the term outside of the parenthesis. It becomes

4x + 20 + 4x + 8

Next step is to add like terms. We would do this by adding each term containing x together and also add the constants together. It becomes

4x + 4x = 20 + 8

8x+ 28

Since 4 is a common factor of both terms, we would factorize 4 out. It becomes

4(2x + 7)

Line segment AB is reflected across the y–axis to form line segment CD. Then, line segment CD is rotated 90° clockwise about the

Maksim231197 [3]

Answer:

The coordinates of EF are E(5,-4) and F(1,-4).

The line segment EF is in QIV

Step-by-step explanation:

The line segment AB has vertices at: A(-4,5) and B(-4,1).

We apply the rule $(x,y)\to (-x,y)$ to reflect AB in the y-axis to obtain CD.

$\implies A(-4,5)\to C(4,5)$

$\implies B(-4,1)\to D(4,1)$

We apply the rule $(x,y)\to (y,-x)$ to rotate CD 90 degrees clockwise about the origin to obtain EF.

$\implies C(4,5)\to E(5,-4)$

$\implies D(4,1)\to F(1,-4)$

The coordinates of EF are E(5,-4) and F(1,-4).
