Final answer:
The expression x^2 + 2y ÷ 2w + 3z can be simplified by substituting the given values for x, y, w, and z. The value of the expression is 38.
Step-by-step explanation:
The expression x^2 + 2y ÷ 2w + 3z can be simplified by substituting the given values for x, y, w, and z. We have x = 5, y = 8, w = 2, and z = 3.
Substituting these values, we get:
x^2 + 2y ÷ 2w + 3z = 52 + 2(8) ÷ 2(2) + 3(3) = 25 + 16 ÷ 4 + 9 = 25 + 4 + 9 = 38.
Therefore, the value of the expression is 38.
