EXPLANATION:
If g= 3 we can replace g with 3.
Now we have h-5 x 3
and if h= 17, we can replace h with 17.
Now we have 17 - 5 x 3.
because of pemdas, multiplication is first
5 x 3 is 15,
17 - 15 is 2.

Answer:
82
Step-by-step explanation:
f(x) = 5x - 3
g(x) = 2x + 9
f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)
f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82
