Question

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

Answer 1

Yes

Answer 2

Can it not be simplified any more?

Answer 3

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

Answer 4

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

Answer 5

Yes

Answer 6

Thank you

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

thank you very much

Answer 11

welcome

Answer 12

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