Answer:

Step-by-step explanation:
The number of parrots in t years after 2010 can be modeled by the following function:

In which P(0) is the number of parrots in 2010 and r is the growth rate, as a decimal.
608 parrots in the forest in 2010.
This means that 
Then

When the scientists went back 5 years later, they found 4617 parrots.
This means that 
We use this to find 1 + r. So



![1 + r = \sqrt[5]{\frac{4617}{608}}](https://tex.z-dn.net/?f=1%20%2B%20r%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7B4617%7D%7B608%7D%7D)

So

Answer:
Use the Quadratic formula
Ambiguous expression. I think you meant:
3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
x+5
There's no "answer." All you can do here is to combine the terms and simpify the resulting sum.
