Question

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.. . . (C + D)2. 2(C + D). C2 + D2. C2 − D2

Answer 1

The question or the problem wants to choose among the following expression is the largest, base on the data presented in the problem, the possible answer among the following choices is C2+D2. I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

Answer:

the largest is:   $C^2+D^2$

Step-by-step explanation:

We are given the expression C>D>0.

As C and D represent two different school populations. This means that C and D will be natural numbers.

C+D<2×(C+D)

Also $C^2+D^2>C^2-D^2$.

the largest among these expressions is  $C^2+D^2$
