2

0.5

-0.5

To answer the question above as to the scale factor of the dilation  which in an image not provided, two circles are centered at A, The circle containing B was dilated to produce circle containing B'. The answer is number 1.

I hope my answer has come to your help. God bless and have a nice day ahead!

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
