Work Shown:

Solve the equation for y

-13y - 5 = 8

-13y = 8+5

-13y = 13

y = 13/(-13)

y = -1

Then use this y value to compute 4y+7

4y+7 = 4(-1)+7 = -4+7 = 3

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
