Algebra.Com's Answer #520679 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! Good so far . Now how can you use that information and the perimeter is 28 to find out what x equals? \n" ); document.write( "P=2W+2L\r \n" ); document.write( "\n" ); document.write( "28=2W+2L \n" ); document.write( "3W-2=L \r \n" ); document.write( "\n" ); document.write( "We now have two equations with the unknowms \n" ); document.write( " |
