Algebra.Com's Answer #75839 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! let x=width; so 5x+3=length ... area=(length)(width)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "76=(5x+3)(x) ... 76=5x^2+3x ... 0=5x^2+3x-76\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "use quadratic formula to find x \n" ); document.write( " |
