Given:
\n" ); document.write( "(1) r < s < q,
\n" ); document.write( "(2) r*s = 44.6 and
\n" ); document.write( "(3) s*q = 68.4
\n" ); document.write( "Solve (2) for r and get
\n" ); document.write( "(4) r = 44.6/s
\n" ); document.write( "Solve (3) for q and get
\n" ); document.write( "(5) q = 68.4/s
\n" ); document.write( "Now put (4) and (5) into (1) to get
\n" ); document.write( "(6) 44.6/s < s < 68.4/s or
\n" ); document.write( "(7) 44.6 < s^2 < 68.4
\n" ); document.write( "Now use (4) and (5) to get rq as
\n" ); document.write( "(8) r*q = (44.6*68.4)/(s^2)
\n" ); document.write( "Using the limits for s^2 given by (7), we get the answer
\n" ); document.write( "(9) 44.6 < r*q < 68.4
\n" ); document.write( " \n" ); document.write( "
\n" );
