Which expression best represents the difference between triple a number and double a number? A) 3x - 2x Eliminate B) 2x - 3x C) x3 - x2 D) x2 - x3

The correct answer is A) 3x - 2x

Step-by-step explanation:

When finding a difference, always list the first expression first. Since it mentions triple a number, the 3 would have to come first.

Also, since it is tripling a number, we want to multiply it by 3, not multiply it by itself as options C and D do.
