Algebra.Com's Answer #105350 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! 54 = 2H+2W (Height and Width) Length would work the same, but it says height. \n" ); document.write( "2H = W+3, so W = 2H - 3\r \n" ); document.write( "\n" ); document.write( "Sub for W\r \n" ); document.write( "\n" ); document.write( "54 = 2H + 2(2H-3) \n" ); document.write( "54 = 2H + 4H - 6 \n" ); document.write( "60 = 6H \n" ); document.write( "H = 10 \n" ); document.write( "W = 17 \n" ); document.write( " \n" ); document.write( " |
