Answer:
a²+2a-8
Step-by-step explanation:
The sides of a right triangle can be found using the Pythagorean Theorem: a^2+b^2=c^2
c is the hypotenuse (the longest side) of the right triangle and a and b are the two other legs. Knowing any two sides of the right triangle, you can find the other using this formula.
Hope this helps!
Observe that

In the original equation, divide both sides by
:


Next,

where
is any integer. Then

Fix
to ensure
, so that

Answer: x=15
Step-by-step explanation:
To solve problems like this you need to simplify the equations on both sides and then isolate your variable x.
The answer is -8 (-8=2*-4)
