Why dont you try to solve it :)

2. anonymous

i did i got 3. am i right?

3. hba

Can you show me the working @TiaW

4. anonymous

yeah hold on

5. hba

I am waiting.

$3\sqrt{(x+4)-2}=13$

7. anonymous

is it this?

8. anonymous

@03225186213 yes

9. anonymous

i redid it. i got 21

3[rt(x+4)] - 2 = 13 3[rt(x+4)] = 15 rt(x+4) = 5 x+4 = 25 x = 25 - 4 x = 21

11. anonymous

am i right?

12. hba

You said -2 was also in the root ?

13. anonymous

divide both sides by 3 take square on both sides add 2 to both sides and at last subtract 4 from both sides

14. hba

If not you are right.

15. anonymous

@hba no its not

16. hba

Well then you are right :) @TiaW
