Answer:
so first you do the work than check
Step-by-step explanation:
Use the Pythagorean theorem:

c - a hypotenuse
a, b - legs
We have: a = 9 and c = 12. Substitute:

<em>subtract 81 from both sides</em>

A Pythagorean triple consists of three positive integers a, b and c, such that
.
is not positive integer.
<h3>The sides of the triangle do not form a pythagorean triple.</h3>
So first, this is point slope form. The first step is to distribute.)

Then add 4 to both sides.

Then add 2x and it becomes
Answer:
7g+3h
Step-by-step explanation:
you combine like terms by adding 3g and 4g and subtracting 2h from 5h.
