Question

How do the expressions 7+h2−5 and 10(h+2)−2h compare when h = 9?

7+h2−5 Response area 10(h+2)−2h when h = 9.

Answer 1

7 + h^2 -5 < 10(h + 2) - 2h

Explanation:

1. Substitute h=2 into the two equations:

7 + 9^2 - 5 = 7 + 81 - 5 = 83

10(9 + 2) - 2*9 = 110 - 18 = 92

2. Compare the answers you got after substituting h = 9:

83 < 92

3. Therefore:

7 + h^2 -5 < 10(h + 2) - 2h
