\"x%2Bx%2B%28x%2B4%29%2B%28x%2B4%29=54\"
\n" ); document.write( "perimeter is \"highlight%28x%2Bx%2B%28x%2B4%29%2B%28x%2B4%29%29\".
\n" ); document.write( "That is an expression for perimeter in terms of x. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Did you want to solve for x, knowing the perimeter?
