The length of a rectangle is the square root of 100 times an unknown number, x. the width is one-half an unknown number, y, less three-halves x. if the area of the rectangle is 125 cm2, find an equation that would give the width of the rectangle given the length.

correct answer is b. 27/8

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
