14 is 70% of 20.
They played 20 games
48m^5n: 3*2^4*m^5n
81m^2n^2: 3^4m^2n^2
GCF: 3*m^2n
Answer:
1) 20%
2) Choice a.
Step-by-step explanation:

1)
is the population initially.
is the population after a year.
represents the population increase factor.
So let's evaluate that fraction:


0.2=20%
2) Let's figure out the population growth in terms of months instead of years.

We want t to represent months.
A full year is 12 months, in a full year we have that 
So we want a new P such that
since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a) 
b) 
c) 
d) 
So a is the function we want.
Also another way to look at this:
where
is in years.
where
is in months.
And 
Difference = 48-19
= 29
production decrease = 29 × 100/ 48
= 60.41%
Answer:
8n - 3.9
Step-by-step explanation:
Given
- (- 8n + 3.9 ) ← multiply each term in the parenthesis by - 1
= 8n - 3.9
