A rectangle is 8 inches longer than it is wide. Which function models the perimeter P, in inches, of the rectangle, given that its width is w?
P(w) = W2 + 8
P(w) = 18W
P(w) = 2w + 8
P(W) = 4w + 16

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
