## anonymous 5 years ago Does the the distance from (-1,7) to (-5,-4)= sqrt(137)? I'm not sure if I did it right.

1. anonymous

Yes

2. anonymous

Can it not be simplified any more?

3. anonymous

Nope. You can find it in decimals if you want to

4. anonymous

I need it in the form of a root. $\sqrt{137}$ is the final answer?

5. anonymous

Yes

6. anonymous

Thank you

7. anonymous

$\sqrt{(-1+5)^2+(7+4)^2}=\sqrt{4^2+11^2}=\sqrt{16+121}=\sqrt{137}$ just practicing my latex

Using the same formula, then the distance from (-4,-6) to (4,-5) should be $\sqrt{65}$ correct?

9. anonymous

yes. distance from -4 to 4 is 8. distance from -6 to -5 is 1 $8^2+1^2=65$

10. anonymous

thank you very much

11. anonymous

welcome

one last question. $\sqrt{8}$=$2\sqrt{2}$ and not just 2 right?
