Algebra.Com's Answer #180193 by dabanfield(803)![]() ![]() ![]() You can put this solution on YOUR website! need to find the length of a rectangle which is 4 more than the width. if the area of the triangle is 96 sq inches, i have to find the dimensions of the triangle.\r \n" ); document.write( "\n" ); document.write( "Let x be the width of the rectangle.\r \n" ); document.write( "\n" ); document.write( "Then the length is x + 4.\r \n" ); document.write( "\n" ); document.write( "Since the area of the rectangle (length times width) is 96 we have:\r \n" ); document.write( "\n" ); document.write( "x*(x+4) = 96 or \n" ); document.write( "x^2+4x-96 = 0\r \n" ); document.write( "\n" ); document.write( "Solve this quadratic equation for x (the width). Then calculate the length as x+4. \n" ); document.write( " |
