Answer 3

@Wholock

Answer 4

\[\sqrt{(x_2^{2}-x_1^{2})+(y_2^{2}-y_1^{2})}\]
I think you know that expression. don't you?

Answer 5

Yes

Answer 6

Simply substitute:
You got:
\[\sqrt{(6+1)^2+(16-14)^2}\]
\[=\sqrt{53}=7.28\]

please, check my result and yours to be sure.

Answer 7

Would it be 7.3 since I have to round it to the nearest tenth?
