I think they wrote the wrong answers but if y’all find out which one it is thanks

8x^2+16x+16

Step-by-step explanation:

The combined area is the sum of both expressions.

2x^2-13x+21+6x^2+29x-5

8x^2+16x+16

8(x^2+2x+2)

You're right. The multiple choice is just wrong.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
