Answer: 22.4
Step-by-step explanation:
The distance formula can be used to solve this problem.

We can plug in our x and y values to find the distance.





Our distance between the points is 22.4.
First, let's make it an improper fraction:
-9/2 * 5/2 = -45/4 = -11 1/4
-11 1/4
Yes. Since neither are rounded, 46.2 would be greater.
A stop sign has 8 sides and all angles are the same, so it is a regular octagon.
