The length of a rectangle is 3 inches more than the width. The perimeter of the rectange is 24 inches.
\n" ); document.write( "a.) define variables
\n" ); document.write( " L-length, W-width, P-perimeter
\n" ); document.write( "b.) write the expression for the length in terms of the width
\n" ); document.write( " L=3+W
\n" ); document.write( "c.) substitute what you know into the equation. Be sure you only have one variable
\n" ); document.write( "The step you're missing is the equation of the perimeter of a rectangle
\n" ); document.write( "\"P=2L%2B2W=24\"
\n" ); document.write( "\"2%283%2BW%29%2B2W=24\"
\n" ); document.write( "\"2%283%29%2B2%28W%29%2B2W=24\"
\n" ); document.write( "\"6%2B4W=24\"
\n" ); document.write( "\"6-6%2B4W=24-6\"
\n" ); document.write( "\"4W=18\"
\n" ); document.write( "\"W=18%2F4=9%2F2\"
\n" ); document.write( "W=4.5 inches
\n" ); document.write( "d.) what is the length of the rectangle?
\n" ); document.write( " \"L=3%2B9%2F2=6%2F2%2B9%2F2=15%2F2\"
\n" ); document.write( "L=7.5 inches\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "write the expression for the length in terms of the width
\n" ); document.write( "c.substitute what you know into the equation. Be sure you only have one variable
\n" ); document.write( "d.what is the length of the rectangle?
\n" ); document.write( "
\n" );
