Algebra.Com's Answer #463613 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Shorter leg = x \n" ); document.write( "Longer leg = 6 + 2x \n" ); document.write( "Hypotenuse = 9 + 2x \n" ); document.write( "(6 + 2x)^2 + x^2 = (9 + 2x)^2 \n" ); document.write( "36 + 24x + 4x^2 + x^2 = 81 + 36x + 4x^2 \n" ); document.write( "Collect like terms \n" ); document.write( "x^2 - 12x - 45 = 0 \n" ); document.write( "(x + 3)(x - 15) = 0 \n" ); document.write( "x = -3 (No answer) \n" ); document.write( "x = 15 \n" ); document.write( "Shorter leg = 15m \n" ); document.write( "Longer leg = 36m \n" ); document.write( "Hypotenuse = 39m \n" ); document.write( "Proof: \n" ); document.write( "15^2 + 36^2 = 39^2 \n" ); document.write( " 1521m = 1521m \n" ); document.write( "hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
