Help...

Directrix (directrix):

I don't know what this is.

OpenStudy (anonymous):

It's the lengths of the rectangle on the stain glass assignment.

Directrix (directrix):

Post the stained glass thing in this thread. I don't know which one you used or what the coordinates are.

Directrix (directrix):

That looks familiar.

Directrix (directrix):

Now, what do you want to do here.

OpenStudy (anonymous):

I worked out the problem to solve the lengths for the rectangle using distance formula, but I wanted to know if I completed it correctly.

Directrix (directrix):

Where are the distances that you got?

Directrix (directrix):

Well, use the online distance between two points calculator. http://easycalculation.com/analytical/distance.php

Directrix (directrix):

Rectangle (-3,-2) to (3,-2) should be 6, not square root (52). On the points (the distance between you are getting), you can just count units. If you prefer, use the distance formula and check with the online distance calculator.

for points A & B I got, 6in. I didn't get that for my answer.... 0.o

You have a sign-us error. |dw:1383034874461:dw|
