Answer:
A = P(1 + r)t
Step-by-step explanation:
Or this formula:
![A = P(1 + \frac{r}{n} )](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%20%29)
Answer:
21
Step-by-step explanation:
you do what is parenthesis first so you would do 3 times 2 which is 6 then do 3 times 5 which is 15 well 15 plus 6 equals 21
Answer:
I personally belive it to be an observational study
Answer: Last option
inverse property
Step-by-step explanation:
The property of the inverse sum says that if we have a number b and we add it with its negative -b then
![b - b = 0](https://tex.z-dn.net/?f=b%20-%20b%20%3D%200)
In this case we have that:
![x = a + bi](https://tex.z-dn.net/?f=x%20%3D%20a%20%2B%20bi)
and
![y = -b - bi](https://tex.z-dn.net/?f=y%20%3D%20-b%20-%20bi)
Note that
![y = -x](https://tex.z-dn.net/?f=y%20%3D%20-x)
Therefore:
![x + y = x -x= a + bi - a - bi = 0](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20x%20-x%3D%20a%20%2B%20bi%20-%20a%20-%20bi%20%3D%200)
the answer is the last option
I believe it would be 15. 10+20+15=45/3=15
