Question

The perimeter of a stop sign has a perimeter of 16x^2 - 80x. What is the length of one side?

Answer 1

A stop sign is a regular octagon, so the length of one side is merely one eighth of the total perimeter:
\[\frac{16x^2-80x}{8}=\cdots\]

Answer 2

22??

Answer 3

Answer 4

No. You shouldn't get a number as your final answer, unless you're specifically told the value of \(x\).
\[\frac{16x^2-80x}{8}=\frac{16\left(x^2-5x\right)}{8}=\frac{8\cdot2\left(x^2-5x\right)}{8}=2\left(x^2-5x\right)\]

Answer 5

oh ok . so thisi is your answer 2(x^2-5x)

Answer 6

Yes
