Which set of lengths could be the side lengths of a right triangle?

A. 7 in., 7 in., 10 in.
B. 4.5 ft, 6 ft, 7.5 ft
C. 10 m, 11 m, 15 m
D. 8 cm, 10 cm, 13 cm

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
