Algebra.Com's Answer #453909 by tommyt3rd(5050)![]() ![]() You can put this solution on YOUR website! length of a rectangle is 5 inches more than double its width means:\r \n" ); document.write( "\n" ); document.write( "l=2w+5\r \n" ); document.write( "\n" ); document.write( " the perimeter is 70 inches means:\r \n" ); document.write( "\n" ); document.write( "2l+2w=70\r \n" ); document.write( "\n" ); document.write( "or l+w=35\r \n" ); document.write( "\n" ); document.write( "subbing in for l and simplifying...\r \n" ); document.write( "\n" ); document.write( "(2w+5)+w=35\r \n" ); document.write( "\n" ); document.write( "3w=30\r \n" ); document.write( "\n" ); document.write( "so w=10\r \n" ); document.write( "\n" ); document.write( "then that means \r \n" ); document.write( "\n" ); document.write( "l+10=35\r \n" ); document.write( "\n" ); document.write( "and so l=25\r \n" ); document.write( "\n" ); document.write( "the dimensions must be: 25 inches x 10 inches \n" ); document.write( " |
