a dilation with a scale factor of 4, is multiplication by 4 each side, so we need the measure of the side CD and then multiply by 4 to find C'D'
we can notice tht length of CD, is 3 squares,multiplying by 4 the new length is 3x4= 1 2 squares
Answer: Transitive property of congruence
Ypu would subtract Y from the other points Y

Then you would subtract X from the ither points X.

Then you would put the Y value over the X

Then simiplify
11a:
3x+5=5x-57
3x-5x=-57-5
-2x=-62
x=31
11b:
2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60
x=5
hope this helped !!
2-5 x 1/2 = 0.2 (Length x Width)
