You can put this solution on YOUR website!
length = 2x - 8\r
\n" ); document.write( "\n" ); document.write( "width = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area = 640\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "640 = (2x-8)(x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then substitute x value into the length and width expressions given above.\r
\n" ); document.write( "\n" ); document.write( "Can you finish?\r
\n" ); document.write( "\n" ); document.write( "
