Answer:

36

Step-by-step explanation:

First substitute x for 4 in "g(x) = 5x + 1", and x for 3 in "k(x) = x2 + 2x. (Btw I'm guessing that x2 is actually x^2.)

Now you have:

g(4) = 5(4) + 1 ➡ 5 × 5 = 20 ➡ 20 + 1 = 21

g(4) = 21

k(3) = (3)^2 + 2(3) ➡ 3^2 = 3 × 3 = 9 ➡ 2 × 3 = 6 ➡ 9 + 6 = 15

k(3) = 15

g(4) + k(3) = 21 + 15 = 36

Hope this helps :)
