Answer:
Square both sides and then solves the resulting quadratic equations
Step-by-step explanation:
The equation is 3sqrt(x^2-6)=3sqrt(2x+2)
We can solve this by;
First square both sides;
(3√(x²-6))²= (3√(2x+2))²
We obtain;
9(x²-6)=9(2x+2)
We simplify to obtain a quadratic equation;
x²-6=2x+2
= x²-2x-8=0
Then we solve the quadratic equation;
x²-4x+2x-8=0
x(x-4)+2(x-8)=0
(x+2)(x-8)=0
Values of x = -2 or 8
The perimeter is 38 , As you can see each of the sides provided also have another side across from it that’s equal to the length, therefore you you double the size of the sides that were given , and add them two together.
(Notice that we always have ![y\ge6[tex].)Swap [tex]x](https://tex.z-dn.net/?f=y%5Cge6%5Btex%5D.%29%3C%2Fp%3E%3Cp%3ESwap%20%5Btex%5Dx)
and 
, then solve for :
(this is the inverse)
###
This inverse is valid only for 
. Why?
Suppose we take 
. Then
This would suggest that in the original equation, we should get 
when 
. But when we check this, we end up with
which is clearly not true.
Answer:
sorry but need more info y could be any number
