second side is 2x-4
\n" ); document.write( "third side is x
\n" ); document.write( "17+x>2x-4; -x>-21;x<21
\n" ); document.write( "17+2x-4>x;x>-13
\n" ); document.write( "x+2x-4>17;3x>21, x>7
\n" ); document.write( "x>7 and <21
\n" ); document.write( "Check 8 and 20
\n" ); document.write( "8: sides are 17,8,12: 25>12,29>8, 20<17, it works.
\n" ); document.write( "20: sides are 17,20,36;17+20>36;17+36>20; 20+36>17, it works.
\n" ); document.write( "Try 6. It should not work
\n" ); document.write( "17,6,8: 6+8 is not >17
\n" ); document.write( "7\n" ); document.write( "10<2x-4<22
\n" ); document.write( "Possible lengths would include 8 and 12; 20 and 36
\n" ); document.write( "
\n" ); document.write( "
\n" );
