Algebra.Com's Answer #345720 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! Two consecutive even numbers can be defined as: \n" ); document.write( "x \n" ); document.write( "x+2 \n" ); document.write( ". \n" ); document.write( "x*(x+2) = 5*x +28 \n" ); document.write( ". \n" ); document.write( "x^2 +2x =5x + 28 \n" ); document.write( ". \n" ); document.write( "x^2 -3x -28 = 0 \n" ); document.write( ". \n" ); document.write( "factor \n" ); document.write( ". \n" ); document.write( "(x-7)(x+4) = 0 \n" ); document.write( ". \n" ); document.write( "x = 7 or x = -4 \n" ); document.write( ". \n" ); document.write( "So, there are no two consecutive even integers whose product is 28 more than 5 times the smaller. \n" ); document.write( ". \n" ); document.write( "Done. \n" ); document.write( " |
