Algebra.Com's Answer #57928 by vertciel(183)![]() ![]() ![]() You can put this solution on YOUR website! We don't know the numbers for the length and width, so let's use variables.\r \n" ); document.write( "\n" ); document.write( "Let w be the width.\r \n" ); document.write( "\n" ); document.write( "Length = 5 + 2W\r \n" ); document.write( "\n" ); document.write( "Width = w\r \n" ); document.write( "\n" ); document.write( "Area of rectangle = LW\r \n" ); document.write( "\n" ); document.write( "(5 + 2W)W = 68^2\r \n" ); document.write( "\n" ); document.write( "2W^2 + 5W = 4624\r \n" ); document.write( "\n" ); document.write( "2W^2 + 5W - 4624 = 0\r \n" ); document.write( "\n" ); document.write( "Now, we see that this is a quadratic equation. You can try to factor this equation or just use the quadratic formula.\r \n" ); document.write( "\n" ); document.write( "If you need any more help, let me know. \n" ); document.write( " \n" ); document.write( " |
