What could be so hard. It's a multiple-choice test for Pete's sake.

I forgot where I found this but, this looks like a UIL level question:
If [unparseable or potentially dangerous latex formula], find the min of |x|-|y|.

A quadrilateral inscribed in a circle has side lengths whose squares are 17, 99, 19, and 97. Find the area of the circle.

haha, I guess you didn't notice that it says "squares are 17, 99, 19, and 97", and since 17+99=19+97, so it's right triangles, which the hypotenous is just the diameter, which gives you the area after dividing by 2 and sq it and then times pi.
