At a little-known vacation spot, taxi fares are a bargain. A 16-mile taxi ride takes 18 minutes and costs $14.40. You want to find the cost of a 38-minute taxi ride. What unit price do you need?

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
