You can put this solution on YOUR website!
The height of the box is 9\", so the length x width of the box is 405/9, or 45. So:
\n" ); document.write( "x(x+4)=45
\n" ); document.write( "x²+4x-45=0
\n" ); document.write( "(x+9)(x-5)=0
\n" ); document.write( "x=5 or -9
\n" ); document.write( "The length is 5\", and the width is 9\". So the dimensions of the box are 5\"x9\"x9\". ☺☺☺☺ \n" ); document.write( "
