Point A is at -5 and point B is at 11.<br> What is the distance of AB?
Allisa [31]

Answer:

The distance of AB would be 16.

Step-by-step explanation:

There are several ways to do this. But the way that would probably be easier for u to understand would be if you found the distance of -5 from 0. Remember targ distance is always positive so the distance would be 5 points. Then u have to get to point B or also 11. That means you have to move 11 points Altogether if you add 5 and 11 you get 16.
