1. Hero

You already know the square root of 144. At least I hope you do.

2. TlJesusFreak37

12, but that doesn't help me. /:

3. Hero

Yes, it does, because now you have reduced it to: 12 - sqrt(40) - sqrt(10)

4. TlJesusFreak37

Yes, but that results in 8.8377223398.

5. TlJesusFreak37

Oh wait! Nevermind, thank you.

6. Hero

?

7. Hero

That's now how you're supposed to express the solution.

8. TlJesusFreak37

I thought for a moment 12 - sqrt(40) - sqrt(10) was one of the answers that I had the choice to take, but it was wrong.

9. TlJesusFreak37

I* was wrong. The other choice was 12 - sqrt(10).

10. Hero

Are you sure one of the answer choices wasn't 12 - 3sqrt(10)?

11. TlJesusFreak37

Yes, there was. I should've seen that, but I forgot that sqrt(40) is just double sqrt(10) so then it's 3 times that. Thank you.
