Algebra 2 math help ? =p?

The closest answer would be D. You can automatically rule out A, B, or C, because the hypotenuse is the longest side in a triangle and all of the possible side lengths in A, B, and C, are longer than 25. If you were doing it algebraiclly, then plug in 14 and 20 for a and b, and see what c would be. You would get an answer of 24.41, which is the closest answer you get to 25 in the choices you listed. Hope this explains everything!!! :)
