Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.

Cheers
The answer is already in its simplest form. You can not add the two because the have different variables. Hope this helps ;)))
ANSWER
A (-∞,-2)
B (0,4).
EXPLANATION
The portion of the graph that is above the x-axis is considered positive.
From the graph the curve is above the x-axis on the interval
(-∞,-2) and (0,4).
The first and second options are correct.
