What is the measure of each exterior angle of a pentagon

n = 5 is the number of sides in a pentagon

360/n = 360/5 = 72 is the measure of each exterior angle of the regular pentagon. It has to be a regular polygon or else you could have some exterior angle measures that are different. A regular polygon has all sides equal to one another, and it also has all angles equal to one another.

okay wait before i answer, is this for your points on a graph?

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
