Answer:
64.5%
Step-by-step explanation:
Initial amount N° = ?
Remaining amount after decay = N = ?
k = decay constant = 0.00012 
t = time = 3650 year
fraction remaining will be N/N°
From the decay equation, N = N°
N/N° =
N/N° = 
N/N° = 
N/N° = 0.645 = 64.5%
F(x)+g(x) = (x+7) + (x-3) =
x + 7 + x - 3 =
2x + 4

You can only add exponents if you are multiplying two of the same variable together. For example,
You take them away if you are dividing.
<span>
In a polynomial equation, you can add together two of the same variable if they have the same exponent
</span>
Or you can take them away in a similar fashion,
<span>
But you cannot add two (or more) different exponents,
</span>
(it does not get any simpler)
