I posted this question this morning and nobody answered. So I decided to repost.

 

1. A reflection maps A to B and B to C. If AB=12, what is AC. I tried this problem before and it isn't 24 FYI.

 

2. A dilation with scale factor -3 maps X to X' and Y to Y'. Given X'Y' = 2, find XY.

1. AC = 3/2*12 = 36.

 

2. XY = 2*|-3| = 6.
