Answer:

h = 0.64 ft

Step-by-step explanation:

s =  \frac{14 + 12 + 6}{2}  =  \frac{32}{2}  = 16 \: ft \\  \\ A =  \sqrt{(s - 14)(s - 12)(s - 6)}  \\  \\ A =  \sqrt{(16 - 14)(16 - 12)(16 - 6)}  \\  \\ A =  \sqrt{(2)(4)(10)}  \\  \\ A =  \sqrt{80}  \\  \\ A =  8.94427191\\  \\ A  \approx  8.94 \:  {ft}^{2}

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft

Hey can you please help me posted picture of question :)

If you observe carefully, you can see that the graph is crossing x-axis at the points 1 and 9. This means x = 1 and x = 9 are the roots of the polynomials and x - 1 and x - 9 are thus the factors of the polynomial.

We can express the polynomial as the product of its factors. So the above polynomial can be expressed as (x - 1)(x - 9)

Thus, the answer to the question is option D
