Answer:
-2 + 4i
Step-by-step explanation:
1) remove unnecessary parentheses:
2 + 3i + (-4 + i)
2) calculate difference:
-4 + 2 = -2
-2 + 3i + i
3) collect like terms:
For our answer: -2 + 4i
There ya go, hope I helped good luck!

Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
