Answer:
We need to just focus on first adding up the two numbers inside of the first parenthesis to see if we get our answer.
[tex]4(2.1 + 3.1) - 2(1.4)[/tex]
[tex]4(5.2) - 2(1.4)[/tex]
This proves that option B is a solution and since we can only choose one option that means that we have our answer.
