Algebra.Com's Answer #608559 by josgarithmetic(39625) ![]() You can put this solution on YOUR website! You can choose the sides as x, x, and y, and then the fencing length is 2x+y=200 and xy=3200 for area. This gives the system of equations\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "; \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Discriminant, \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "--------------------------------------- \n" ); document.write( "x=20 and y=160, or x=80 and y=40 \n" ); document.write( "--------------------------------------- \n" ); document.write( " |
