Answer:
The answer is "
"
Step-by-step explanation:
For point 1:
For point 2:
Adding
equation and multiply by 2 in the equation
so we get 
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.

Percent sold=sold/original times 100
sold=816
original=850
percent sold=816/850 times 100
percent sold=0.96 times 100
percent sold=96%
28 + 6 = 34 and 34 - 3 = 31!!!!!!!
