Answer:
9πi/2
Step-by-step explanation:

Let f(z) = (5z² + 4) / (z + 3).

Using Cauchy's integral formula:

Answer: c = 8
Step-by-step explanation:
Simplifying
9c + -3c = 48
Combine like terms: 9c + -3c = 6c
6c = 48
Solving
6c = 48
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '6'.
c = 8
Simplifying
c = 8
