Step-by-step explanation:

Step 1: Let's simplify step-by-step.

$4n^5 + 3.5n^5 - 2.1n^5$

$= 4n^5 + 3.5n^5 + -2.1n^5$

Step 2: Combine Like Terms:

$= 4n^5 + 3.5n^5 + -2.1n^5$

$= (4n^5 + 3.5n^5 + -2.1n^5)$

$= 5.4n^5$

Answer:

$=5.4n^5$

Hope this helps.

Hi there
First find the rate of growth between
1992 and 1998
The formula is
P=Ae^rt
P the population in 1998. (76 million)
A the population in 1992 (72 million)
E constant
R rate of growth?
T time 1,998−1,992=6 years
We need to solve for r
R=[log (p/A)÷log (e)]÷t
R=(log(76÷72)÷log(e))÷6
R=0.009

Now find the population in 2012
P=Ae^rt
P ?
A 72 million
R 0.009
T 2,012−1,992=20 years
So
P=72×e^(0.009×20)
P=86.2 round your answer to get
P=86 million

Good luck!

Three layers of boxes that are 1 ft high will be 3 ft high.

The height of the freezer space is 3 feet.
