Lets show the shorter side \n" ); document.write( "with x and the longer side by 2x-3. Ok, with this we can write an equation as: \n" ); document.write( "x+x+(2x-3)+(2x-3)=24 Combine like terms. \n" ); document.write( "6x-6=24 Add 6 to both sides. \n" ); document.write( "6x=30 Divide both sides by 6 \n" ); document.write( "x=5 So 5 cm is the length of the shorter sides. Plug in 5 to (2x-3) gives us: \n" ); document.write( "7 cm for the longer sides. \n" ); document.write( "RJ Toftness \n" ); document.write( "www.math-unlock.com \n" ); document.write( " \n" ); document.write( " |
