Evaluate 8a + 3b - 10 + c^2 when a = 2, b = 5, and c = 4

To evaluate the expression, substitute the given values of a, b, and c into the expression:

8a + 3b - 10 + c^2 = 8(2) + 3(5) - 10 + 4^2
= 16 + 15 - 10 + 16
= 32 + 15 - 10
= 47 - 10
= 37

Therefore, when a = 2, b = 5, and c = 4, 8a + 3b - 10 + c^2 is equal to 37.
