Question

I really need help. Evaluate each expression for g = -7 and h = 3 and match it to its value.

Answer 1

9514 1404 393

Answer:

1. 10
2. 46
3. 2
4. -21
5. -10
6. -4

Explanation:

Put the numbers where the letters are and do the arithmetic.

h - g = 3 - (-7) = 3 + 7 = 10

g² - h = (-7)² -3 = 49 -3 = 46

g + h² = -7 +3² = -7 +9 = 2

gh = (-7)(3) = -21

g - h = -7 -3 = -10

g + h = -7 +3 = -4
