\n" );
document.write( "  (x+4)(x)(3/4) = 9 in^3
\n" );
document.write( "Solving for x
\n" );
document.write( "  x^2 + 4x = 9(4/3)
\n" );
document.write( " x^2 + 4x -12 = 0

document.write( " (x+6)(x-2) = 0
\n" );
document.write( " (x+6) = 0 , x = -6  throwing out negative solution
\n" );
document.write( " (x-2) = 0 , x = 2in, the width and the length is 6in
