15 points! what is the length of ab? use the distance formula to you decide.

34

Step-by-step explanation:

The scale of factor is 2. Then, you must multiply the coordinates of the endpoints AB by 2 to obtain the coordinates od the enpoints A'B':

Substitute values into the formula, then you obtain that the length A'B' is:
