Evaluate each expression if a=1/2 b=15 and c=9. c2 + a (2 is a exponent) 2ac. b2 - 5c (2 is exponent). here is a picture if you don't know sorry.

C2 + a = 81.5
2ac = 9
B2 - 5c = 180

let me know if you need the work

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.
