## anonymous 3 years ago solve for x: sqrt x+16 - sqrt x-2=0 A. 3 B. 7 C. 9 D. 15

1. anonymous

@jim_thompson5910 i got 9

2. anonymous

It cannot be this way! $\sqrt{x+16}-\sqrt{x-2}=0$

3. anonymous

so what would be my answer then?

4. anonymous

is the question the way I wrote?

5. anonymous

yep

6. anonymous

if the question is exactly like I wrote, then there can be no solution for it!

7. anonymous

for the second part the sqrt is only over 2x

8. anonymous

check the question and use the equation editor below to enter the equation

9. anonymous

I mean x lol

10. anonymous

see..!!

11. anonymous

so, like this?$\sqrt{x+16}-\sqrt{x}-2=0$

12. anonymous

yes:)

13. jim_thompson5910

if the equation is $\sqrt{x+16}-\sqrt{x}-2=0$, then the answer is x = 9 like you got katlin95, so congrats

14. anonymous

then yes.
