How do I solve this?
\n" ); document.write( "Two sides of a triangle measure 3 inches and 7 inches. Between which two values must the third side be?
\n" ); document.write( "

\r\n" );
document.write( "The sum of any two sides of a triangle is strictly greater than the third side.\r\n" );
document.write( "\r\n" );
document.write( "x + 3 > 7, 3 + 7 > x, x + 7 > 3\r\n" );
document.write( "\r\n" );
document.write( "The third one is obviously true, so we need only look at the first two\r\n" );
document.write( "\r\n" );
document.write( "x + 3 > 7, 3 + 7 > x \r\n" );
document.write( "    x > 4     10 > x\r\n" );
document.write( "\r\n" );
document.write( "So 4 < x < 10\r\n" );
document.write( "\r\n" );
document.write( "So the third side must be between 4 and 10 inches, exclusive of both.\r\n" );
document.write( "\r\n" );
