SOLUTION: Okay, so, on my homework there is a right triangle. Side A is equal to 3x+3 and the hypotenuse is equal to 4x-3. I'm not sure how to plug that into the equation a^2+b^2=c^2 though.

You can put this solution on YOUR website!
You are given:
+C+=+4x+-+3+
+A+=+3x+%2B+3+
You need to find B
-------------------
+A%5E2+%2B+B%5E2++=+C%5E2+
+B%5E2+=+C%5E2+-+A%5E2+
+B%5E2+=+%28+4x-3+%29%5E2+-+%28+3x+%2B+3+%29%5E2+
+B%5E2+=+16x%5E2+-+24x+%2B+9+-+9x%5E2+-+18x+-+9+
+B%5E2+=+7x%5E2+-+42x+
+B+=+sqrt%28+7x%2A%28+x+-+6+%29%29+
Hope this helps
