Answer:

A. 693

Step-by-step explanation:

The question is asking you to input 7 into both functions and then multiply them together.

First insert 7 into f(x) = 7 + 2x,   7 times 2 is 14, plus 7 = 21

do the same with g(x) = 5x - 2,   5 times 7 is 35, minus 2 = 33

fg(7) is saying to multiply fg together as a variable next to another variable does. leaving the answer as 693.
