Algebra.Com's Answer #71116 by mathslover(157)![]() ![]() You can put this solution on YOUR website! Let x be the maximum possible width of the path\r \n" ); document.write( "\n" ); document.write( "length of the garden including the path = 35 + 2x ( 2x because x for each side) \n" ); document.write( "width of the garden = 25 + 2x\r \n" ); document.write( "\n" ); document.write( "total area of the garden with the path = (35+2x)(25+2x) \n" ); document.write( "also area of the garden without the path= 35* 25 \n" ); document.write( "area of the path = (35+2x)(25+2x) - 35*25 \n" ); document.write( "Now the area should be less than or equal to 325 sq feet because that is the amount of crushed gravel Al has got.\r \n" ); document.write( "\n" ); document.write( "For maximum path, area of the path = 325 \n" ); document.write( "=> (35+2x)(25+2x) - 35*25 =325 \n" ); document.write( "32*25 + 70x + 50x +4x^2 -35*25 = 325\r \n" ); document.write( "\n" ); document.write( "4x^2 + 120x - 325=0\r \n" ); document.write( "\n" ); document.write( "4x^2 + 130x -10x -325=0\r \n" ); document.write( "\n" ); document.write( "2x(2x+65) - 5(2x+65)=0 \n" ); document.write( "(2x+65)(2x-5)=0 \n" ); document.write( "x=5/2 ignoring the negative -65/2\r \n" ); document.write( "\n" ); document.write( "Maximum width of the path of 2.5m\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
