Algebra.Com's Answer #664726 by jorel555(1290)![]() ![]() ![]() You can put this solution on YOUR website! Let n be the length of the shortest leg. Then the other leg is n+1; and the hypotenuse is n+9. So: \n" ); document.write( "n²+(n+1)²=(n+9)² \n" ); document.write( "2n²+2n+1=n²+18n+81 \n" ); document.write( "n²-16n-80=0 \n" ); document.write( "(n-20)(n+4)=0 \n" ); document.write( "n=20 or -4 \n" ); document.write( "Throwing out the negative result, we get the length of the shorter leg to be 20 inches, the longer leg to be 21 inches, and the hypotenuse is 29 inches. ☺☺☺☺ \n" ); document.write( " |
