HELP!

OpenStudy (anonymous):

I got 32

OpenStudy (anonymous):

\[d = \sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]

OpenStudy (anonymous):

Is that what you used?

OpenStudy (anonymous):

Yea I used it

OpenStudy (anonymous):

\[3\sqrt{2}-\sqrt{2}=?\]

OpenStudy (anonymous):

\[2\sqrt{2}\]

OpenStudy (larseighner):

just eyeballing it I get \( 2\sqrt 5 \)

OpenStudy (larseighner):

diff of the y values is 4, squared 16 diff of the x values \( 2\sqrt 2 \) square = 4(2) thats 24 the root of that is \( \sqrt{24} = 2\sqrt{6} \) Okay so the eyeballing did not work out too well.
