x = length of the pieces
\n" ); document.write( "2nd piece = x
\n" ); document.write( "3rd piece = 1/2x+4
\n" ); document.write( "1st piece = 3rd piece - 2 = (1/2x+4)-2
\n" ); document.write( "Now lets add the pieces together and have them = 18;
\n" ); document.write( "x + 1/2x+4 + (1/2x+4)-2 =18
\n" ); document.write( "x+ x+4+2=18
\n" ); document.write( "2x+6=18
\n" ); document.write( "2x=12
\n" ); document.write( "x=6
\n" ); document.write( "Now we have the length of the 2nd, lets plug this into the others to find their length;
\n" ); document.write( "3rd = 1/2(6)+4
\n" ); document.write( "3rd = 3+4= 7
\n" ); document.write( "1st = 7-2 = 5
\n" ); document.write( "check;
\n" ); document.write( "5+6=11+7=18
\n" ); document.write( ":)
\n" ); document.write( "
\n" );
