The water level of a lake varies inversely with the air temperature. When the air temperature is 75°, the water level is 30 feet.
What is the air temperature, when the lake is 50 feet deep?

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
