b.
Answer to Problem 45PPS
Yes, the value of h has to be greater than 6.
Explanation of Solution
Given:
From subpart (a),
The polynomial can be factored as
Calculation / Explanation:
Consider the factored expression,
When the value of h is substituted as 6, the value of h becomes zero.
Therefore, the value of h has to be greater than 6 inches.
Conclusion:
Thus, the value of h has to be greater than 6.
