Two sides of an equilateral triangle have lengths 3x+1 and -2x+26. Which of 21-x or 3x-4 could be the length of the third side\r
\n" ); document.write( "\n" ); document.write( "3x+1 = -2x+26
\n" ); document.write( " 5x = 25
\n" ); document.write( " x = 5\r
\n" ); document.write( "\n" ); document.write( "Lenght of any side = 3x+1 = 3(5)+1 = 16\r
\n" ); document.write( "\n" ); document.write( "(21-x) is the length of 3rd side
\n" ); document.write( "
\n" );
