Answer: C
Step-by-step explanation:
You can solve this by first multiplying both sides of the fraction by the conjugate of the denominator.
In this case, the conjugate is (8 - 2i).
So:
![\frac{3-5i}{8+2i} *\frac{8-2i}{8-2i}](https://tex.z-dn.net/?f=%5Cfrac%7B3-5i%7D%7B8%2B2i%7D%20%2A%5Cfrac%7B8-2i%7D%7B8-2i%7D)
Simplify:
![\frac{24-46i+10i^2}{64 - 4i^2}](https://tex.z-dn.net/?f=%5Cfrac%7B24-46i%2B10i%5E2%7D%7B64%20-%204i%5E2%7D)
Simplify again, knowing that i^2 = -1
![\frac{14 -46i}{68}](https://tex.z-dn.net/?f=%5Cfrac%7B14%20-46i%7D%7B68%7D)
Then, divide both numbers in the numerator by 68 to get your answer.
![\frac{7}{34} -\frac{23i}{34}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B34%7D%20-%5Cfrac%7B23i%7D%7B34%7D)

Answer:
20cm squared
Step-by-step explanation:
Hello,
4 is to 78 as x is to 100, we write it as a ratio:
We have the following values:
Total people: 31
People per team: 4
The number of teams will then be:
N = (31) / (4)
N = 7.75
Round to the previous whole number.
N = 7
There are 7 teams.
Answer:
they can make about 7 teams.
