Answer:

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

Step-by-step 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
