um...all of them seem like possible answers

anonymous · Answer

i feel like an idiot. :(

anonymous · Answer

is there an answer that you think it could be

anonymous · Answer

maybe 5,5

Okay, the perimeter of a square is 4*side length.  If our perimeter is 12, that means our side length must be 3.

Which of the answer choices are a distance of 3 away from (5,-2)?

whpalmer4 · Answer

It might be helpful to plot the points  (9,-2), (8,-2), (5,5) and (5,-1) followed by (5,-2) and see which one is 3 units away

anonymous · Answer

5,5

whpalmer4 · Answer

Did you do as I suggested and plot the points?

anonymous · Answer

yes, i did

whpalmer4 · Answer

Can you show me a picture of your graph?  I'm curious how you could think that (5,-2) and (5,5) are 3 units apart...

whpalmer4 · Answer

They have the same x coordinate, I agree.  That means the y coordinate values must differ by 3.  Does $-2-5 = 3$?  Does $5 - (-2) = 3$?

Are the two little circles 3 units apart?

anonymous · Answer

so i think it would be B

whpalmer4 · Answer

Why have you gone to a different problem when you haven't correctly completed this one involving the same concept, yet?

anonymous · Answer

cause i think that it is (B)
