Pythagorean theorem, anyone?

anonymous · Answer

Can you just tell me the steps of how I would get my answer? That's simple.

anonymous · Answer

It's pythagorean distance formula: distance between x's is 9, between y's is 11, and between z's is 8. (x2-x1, y2-y1, etc.)
Square all those, add them together and take the square root of the sum.

Thank you :D

or, $$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}$$
