Factoring is an important process that helps us understand more about our equations. Through factoring, we rewrite our polynomials in a simpler form, and when we apply the principles of factoring to equations, we yield a lot of useful information. There are a lot of different factoring techniques.
so to solve this you would distribute the 3 to the (2x-5)
(6x-15)
so the answer is (6x-15)
Use the Pythagorean theorem:

The length of the hypotenuse is approximately 14.1 in.
The Equation is already written in the form y=mx+c there is nothing to solve
The m is the coefficient of the equation only if the equation is written in the general form y=mx+c
judging from the given equation m=9 and c=0
I hope I helped you.
