Secants P N and L N intersect at point N outside of the circle. Secant P N intersects the circle at point Q and secant L N intersects the circle at point M. The length of P N is 32, the length of Q N is x, the length of L M is 22, and the length of M N is 14. In the diagram, the length of the external portion of the secant segment PN is . The length of the entire secant segment LN is . The value of x is .
