Answer
19
Work Step by Step
First, you need to insert your T and V values into their respective places in the equation. You should end up with 9(1) + 6(2(5)-1) - 7(5). Then, through PEMDAS, you can simplify 9(1) into 9, 6(2(5)-1) into 45, and 7(5) into 35. Finally, just simplify 9 + 45 - 35 into 19 and you'll have your answer.
