## anonymous one year ago What is the solution to equation, square root of (2x+8) -6=4

1. anonymous

Helppppp

2. anonymous

Does it look like this? $\large \sqrt{2x+8}-6=4$

3. anonymous

yes!

4. anonymous

Well the first step is to get the 6 to the other side. Can you do that?

5. anonymous

yes you add it to the 4 to get 10. but I have no idea what to do after that

6. anonymous

So now it will look like this $\large \sqrt{2x+8}=10$ So we're going to get x out of the square root by squaring both sides. So $\large \sqrt{2x+8}^{2}=10^{2}$

7. anonymous

so is it going to be, (2x+8)(2x+8)=20?

8. anonymous

No. $\large \sqrt{x}^{2} = x$ So $\large \sqrt{2x+8}^{2} = 2x+8$ And $\large 10^{2}=10 \times 10$

9. anonymous

So 2x+8=100. and then you get ride of the 8 by subtracting on the other side and the divide by 2. would the answe be x=46?

10. anonymous

Yes, that would be it. Good job :)

Thank you!! (:
