11x?

3. zaynahf

Can you simplify the first radical by finding the perfect square that fits in it?

4. meganemma1995

11s isn't an option ):

5. zaynahf

@HorseCrazyGirlForever Try not to just post the answer.. try to explain how ya got there

6. meganemma1995

i believe so

7. zaynahf

So what perfect square fits into 18?

8. UnkleRhaukus

$\sqrt{18x}+\sqrt{2x}$ $=\sqrt{9\times2x}+\sqrt{2x}$ $=\sqrt{9}\times\sqrt{2x}+\sqrt{2x}$ $=\sqrt{3^2}\times\sqrt{2x}+\sqrt{2x}$ $=$

9. HorseCrazyGirlForever

Geez I don't know if that is correct... :(

10. HorseCrazyGirlForever

Could I get some help with my question when you guys are done here? I really need to get it done....

11. meganemma1995

UncleRhaukus, the final answer isn't showing ):

@UncleRhaukus

13. whpalmer4

You're supposed to figure it out!

14. zaynahf

I dont think he wanted it to show, i think he wanted you to do it

15. meganemma1995

ughhhhhh

16. meganemma1995

i need to get this overwith, so if anyone can just give me the answer real quick, i'll give them their medal.

17. whpalmer4

Oh, come on, it's easy! What is 3*3? and what number * itself gives you 9?

18. UnkleRhaukus

$=\sqrt{3^2}\times\sqrt{2x}+\sqrt{2x}$ simplify this bit $$\sqrt{3^2}$$ then combine the like terms
