Answer:

23 and 31

Step-by-step explanation:

substitute x = 2 into f(x) and x = 4 into g(x)

f(2) = 2(2) - 3 = 4 - 3 = 1

g(4) = 5(4) + 2 = 20 + 2 = 22

Then

f(2) + g(4) = 1 + 22 = 23

----------------------------------------------

substitute x = 8 into f(x) and x = 2 into g(x)

f(8) = 5(8) - 3 = 40 - 3 = 37

g(2) = 3(2) = 6

Then

f(8) - g(2) = 37 - 6 = 31
