Question

Which expression is equivalent to 4(2.1+3.1)-2(1.4)?

Answer 1

We need to just focus on first adding up the two numbers inside of the first parenthesis to see if we get our answer.

`4(2.1 + 3.1) - 2(1.4)`

`4(5.2) - 2(1.4)`

This proves that option B is a solution and since we can only choose one option that means that we have our answer.
