\n" ); document.write( "\n" ); document.write( "My Attempt: x(x+7) = 330
\n" ); document.write( " x^2 + 7x = 330
\n" ); document.write( "square root both sides x + 7x = 18.2
\n" ); document.write( " 8x/8 = 18.2/8

Area = length * width
\n" ); document.write( "A = 330m^2
\n" ); document.write( "330 = x(x+7)
\n" ); document.write( "330 = x^2 + 7x
\n" ); document.write( "Subtract 330 from each side
\n" ); document.write( "x^2 + 7x -330 = 0
\n" ); document.write( "Factor
\n" ); document.write( "(x+22)(x-15)
\n" ); document.write( "Since a measurement can't be a negative number, the only possibility is 15.

\n" ); document.write( "One side is 15. Therefore the other side is 22.
\n" ); document.write( "22 * 15 = 330
\n" ); document.write( "22 is 7 more than 15.
\n" ); document.write( "
\n" ); document.write( "
\n" );
