Given that <span>point L is between M and N on MN. Then
MN = ML + LN
31 = h - 15 + 2h - 8 = 3h - 23
3h = 31 + 23 = 54
h = 54/3 = 18
Therefore, LN = 2(18) - 8 = 36 - 8 = 28.

The correct numbers are 55 and 47, because they have a difference of 8 and a sum of 102.
The answer is 11 sorry if I’m wrong
Answer:

Step-by-step explanation:
