Let x = second side \n" ); document.write( "Let 2x+8 = first side \n" ); document.write( "Let 3x = third side\r \n" ); document.write( "\n" ); document.write( "the perimeter is the addition of all three sides so:\r \n" ); document.write( "\n" ); document.write( "x+2x+8+3x = 128 \n" ); document.write( "add the like terms: \n" ); document.write( "6x+8 = 128 \n" ); document.write( "subtract 8 from both sides of the equation: \n" ); document.write( "6x=120 \n" ); document.write( "divide both sides by 6 to get: \n" ); document.write( "x=20\r \n" ); document.write( "\n" ); document.write( "Hope you understand! \n" ); document.write( " |
