Question

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2 10 6. g2 - h -10

Answer 1

1. -4

2. -10

3. 10

4. -21

5. 2

6. 46

Explanation:

Answer 2

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1.
`g-h = -7 + 3 = -4`

2.
`g-h = -7 - 3 = -10`

3.
`h-g = 3 - -7 = 3+10 = 13`

4.
`gh = -7(3) = -21`

5.
`g+h^2 = -7 + 3^2 = -7+9 = 2`

6.
`g^2-h = (-7)^2 -3 = 49 -3 = 46`
