Step-by-step explanation:
Given the complex number
The formula to find the midpoint of two complex number (a + bi) and (c + di) is:





Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.
Answer:
D) b = 
Step-by-step explanation:
First, move all the terms that do not include b to the left side with S:
S = 2ab + 2bc + 2ac
S - 2ac = 2ab + 2bc
Now, factor out 2b from the right side:
S - 2ac = 2b(a + c)
Divide both sides by 2(a + c):
b = 
Finally, multiply out the denominator:
b =
