Question

Which expression represents triple the sum of y + 2? A.) 3(y + 2) B.) 5y C.) 3y +2 D.) 6

Answer 1

A. 3(y+2)

Explanation:

B wouldn't work because it would be safe to assume that it represents the quintuple of the sum. C also wouldn't work because although the y is tripled, the 2 isn't. And D wouldn't work because it is only tripling 2.

A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.
