Suppose a and b represent two different school populations where a> b and a and b must be greater then 0. which of the following expressions is the largest? explain why. show all work necessary. a: 2(a+b) b: (a+b)^2 c: a^2+b^2 d: a^2-b^2

Option: B is correct

Step-by-step explanation:

We know that A and B represents two different school populations.

Hence, A and B will be a positive integer.

Also we are given A>B

Since,

⇒ ( As 2AB is a positive quantity)

Also

Since an positive quantity added to will make the term greater than an positive quantity subtracted from .

 Also

(Since for all n>2)

Hence the largest term among all the terms is .

the answer is d. (1.2, -4.7) on edgn

hope this !
