Suppose C and D represent two different school populations where C > D and C and D must be greater than 0. Which of the following expressions is the largest? Explain why. Show all work necessary. A: (C + D) 2 B: 2 (C + D) C: C2 + D2 D: C2 - D2

Since it doesn't specify what C and D equal, beyond them being greater than zero and C being greater than D, you can assign them random values and solve the problem. So for the sake of showing work, let C equal 2 and D equal 1.

A: (2+1) 2 = 6

B: 2 (2+1) = 6

C: (2) 2 + (1) 2 = 6

D: 2 (2) - 1 (2) = 0

Options A and B are the same equations, and C and D are direct opposites. Does your question allow multiple answers?
