Step-by-step explanation:

Collect like terms and simplify
[tex] -10n+30n=-36-24 \\ 20n = -60 [/tex]
Divide both sides of the equation by 20
[tex] 20n/20 = -60/20 \\ n=-3 [/tex]
Answer:
the area after 6 years is 3,473 km^2
Step-by-step explanation:
The computation of the area after 6 years is as follows:
= Area × (1 - decreased percentage)^number of years
= 4,800 km^2 × (1 - 5.25%)^6
= 4,800 km^2 × 0.9475^6
= 3,473 km^2
Hence, the area after 6 years is 3,473 km^2
