Area: A = LW\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"A%28x%29=%282x-1%29%28x%2B2%29=2x%5E2%2B4x-x-2=2x%5E2%2B3x-2\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the area function is \"A%28x%29=2x%5E2%2B3x-2\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now to find A(5), just plug in x=5 and evaluate:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A%285%29=2%285%29%5E2%2B3%285%29-2=2%2825%29%2B3%285%29-2=50%2B15-2=63\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"A%285%29=63\"
