First, move all the terms to one side
x^2+4x-4-8=0
Then, simplify.
x^2+4x-12=0
After that, factor. Ask yourself: Which two numbers add up to 4 and multiply to -12? That would be -2 and 6. Then, rewrite the expression.
(x-2)(x+6)=0
Lastly, solve for x. 
x=2, -6
Your final answer would be x = -6 or x = 2

Crazy boy [7]

The volume of a sphere is given by the equation V=\frac{4}{3} \pi r^{3}, where V is the volume and r is the radius.


To answer this question, simply plug the correct values into the equation:

V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976


The volume of the air in the balloon is about 113.0976 in3.


Hope this helps!!
