The length of a rectangle is modelled by the expression 3y^2. The width is modelled by the expression 6xy. Write the simplified expression for the perimeter of the rectangle.

if i put something wrong your not gonna like it so rather not say nothing.

2 2/3 hours duhh silly

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
