To fit between two windows, the width of a bookshelf must be no greater than six and one half feet. mrs. aguilar purchases a bookshelf that is 77 inches wide. which statement describes the relationship between the width of the bookshelf and the distance between the windows?

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

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
