You can put this solution on YOUR website!
The perimeter of a rectangle (P) = 2W+2L.
\n" ); document.write( "you are given the length (L) and the width (W).
\n" ); document.write( "So:
\n" ); document.write( "\"P=2%282x-5%29%2B2%283x%2B9%29\"
\n" ); document.write( "\"P=4x-10%2B6x%2B18\"
\n" ); document.write( "\"highlight%28P=10x%2B8%29\"
\n" ); document.write( "--------------------------
\n" ); document.write( "Just plug 4 into x in the above equation to get a value for the perimeter when x=4. i will leave that part to you :-)
