Answer:
A= -4,000m + 39,000
Step-by-step explanation:
If your doing the calculation it would be right
Given: -4,000m + 39,000
-4,000(1) + 39,000 = 35,000ft
-4,000(2) + 39,000 = 31,000ft
I don't know how to explain, but ig if you have the negative 4000, and you mutiply and add 39,000 it would decrease the ft
