Rectangle Dimensions Problem:
\n" ); document.write( "x is length, y is width.
\n" ); document.write( " $\"y=-2%2Bx\"$ and $\"xy=15\"$ and you want the perimeter. First solve for x and y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"xy=x%28x-2%29=15\"$
\n" ); document.write( " $\"x%5E2-2x=15\"$
\n" ); document.write( " $\"x%5E2-2x-15=0\"$
\n" ); document.write( " $\"%28x%2B3%29%28x-5%29=0\"$
\n" ); document.write( "-
\n" ); document.write( " $\"highlight%28x=5%29\"$ and therefore, $\"highlight%28y=3%29\"$ .
\n" ); document.write( "-
\n" ); document.write( "perimeter is $\"2%28x%2By%29\"$ . \n" ); document.write( "
