Algebra.Com's Answer #7611 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Let x = base of triangle \n" ); document.write( "x-3 = height of triangle\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Area = \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Multiply both sides by 2 to clear the fraction: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Quadratic equation, so set equal to zero: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "x=8 base \n" ); document.write( "x-3= 5 height\r \n" ); document.write( "\n" ); document.write( "Reject x=-5, since the base of a triangle cannot be negative.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC \n" ); document.write( " |
