Please help! I don't really understand this :/

Answer:
The answer would be 19
Step-by-step explanation:
You plug in the x and y values, and it looks like this
2(4)^2/8+5(3)
Simplify
2(16)/8+15
32/8+15
4+15
--->19<---
The answer is 19 (See picture below for explanation)
OR:
2 x ([tex]4^{2}[/tex]) ÷ 8 + (5 x 3)
