Key concept for this question is knowing the laws of logarithm. hope this helps and feel free to clarify!
Answer:
(x - 8)(x + 7)
Zeroes: x = 8, x = -7
Step-by-step explanation:
Find factors of -56 that add to -1.
-8 and 7
The factored form is:
(x - 8)(x + 7)
The zeroes for this polynomial are x = 8 and x = -7
The volume of a prism is given by:

We know that the height is x. The length is 25 shorter than x, this can be express as:

The width is 14 longer than x, this can be express as:

Plugging the expressions for the length, the width and the height we have that:

Therefore, the volume of the prism is:
