Algebra.Com's Answer #157804 by nyc_function(2741)![]() ![]() You can put this solution on YOUR website! Let length = 5x - 3\r \n" ); document.write( "\n" ); document.write( "Let width = x\r \n" ); document.write( "\n" ); document.write( "The perimeter is 18\r \n" ); document.write( "\n" ); document.write( "Use the formula: P = 2L + 2W as step one.\r \n" ); document.write( "\n" ); document.write( "Here is the set up:\r \n" ); document.write( "\n" ); document.write( "18 = 2(5x - 3) + 2(x)\r \n" ); document.write( "\n" ); document.write( "When you find x, this will be your width. Then go back to 5x - 3, plug your value for x and simplify to find your length.\r \n" ); document.write( "\n" ); document.write( "Can you finish now? \n" ); document.write( " |
