The face of a playhouse is shown below. The owner wants to refinish the face of it due to his daughter, Maria drawing all over it . If the painting contractor charges $25 a square ft, how much would it cost the owner to have the front of the playhouse painted?

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

step-by-step explanation:

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
