Question

2 times the sum of a and b

Answer 1

2(a + b)

Why?

In the sentence, it says "2 times", which most of the time means that the equation is in some way going to be multiplied by 2. The sentence also says the "sum of a and b", where the word "sum" represents addition. So, when we read over the entire sentence "2 times the sum of a and b", it most likely means that the equation is going to be written as:

2(a + b)

Hope this helps!

Answer 2

2(a + b), since for example, if a was 3 and b was 2, it would equal 2 x 5 = 10
