If

, then you have


By the intermediate value theorem, there will be some number

such that

(i.e.

will have a root in

) if you can guarantee that

or

.
Since the coefficients

are all positive, then you know right away that

, so you need to have

in order for there to be such a

.
This means you need to have

which means (A) must be the answer.

In this triangle by applying Pythagoras theorem.
H²=B²+P²
18²=15²+P²
324=225+p²
324-225=P²
√99=p
9.94
