**math**

you have 2 lengths of 125, so you use up 250. Now you have 50 left, the 2 other sides must be even in order to be a rectangle. So divide 50 by 2 and you get 25. Therefore the rectangles sides are 125,125, 25,2.

plug in -4 for x in the equation. If both sides are equal when ur done, it is a solution.

Okay Sis, I think this is how you do it. The probability of NOT getting the ring in the first piece of the first cake is 9/10, and the probability of NOT getting it in the first piece of the second piece is also 9/10. I believe you multiply .9 by .9 to find your answer. ...

Convex. In a yield sign, you can draw a line from any point to another without the line going out of the shape. However, you can not do this with a concave shape.
