![i = \sqrt{-1}](https://tex.z-dn.net/?f=i%20%3D%20%5Csqrt%7B-1%7D%20)
This is the fundamental property of
i that you'll need to keep in mind when solving any problem with imaginary numbers (5i, 2i, 18i, etc.) or complex numbers (3+2i, 8-5i, etc). Squaring both sides of this definition, we also get that
![i^2=-1](https://tex.z-dn.net/?f=i%5E2%3D-1)
Which we can use to solve this problem. We have:
2/7 = 10/35
1/5 = 7/35
10/35 + 7/35 = 17/35.
Answer:
You will need to use it.

That's what it wants
Answer:
2g + 4h = 43
2g + 2h = 30
Step-by-step explanation:
Answer:
- Tadeo: 12 hours
- Dylan: 2 hours
Step-by-step explanation:
We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...
d +6d = 14
7d = 14 . . . . . . collect terms
d = 2 . . . . . . . divide by the coefficient of d
6d = 6(2) = 12
Tadeo volunteered 12 hours; Dylan volunteered 2 hours.
