Answer:
The value of f[g(2)] is 71.
Step-by-step explanation:
We need to find f[g(2)].
The first step is finding f[g(x)]
We have that:


To find f[g(x)], the first step is replacing each x is f by g(x). So

Now we replace x by 2

The value of f[g(2)] is 71.
A) 68.25+3x<80
b) subtract 68.25 from both sides of the inequality
3x<11.75 divide both sides by 3
x<47/12
Since x must be an integer, the greatest number of cartons that he can purchase is 3. Hope this helps:)
Answer:
There are
rows in the theater.
Step-by-step explanation:
Given terms.
Seats in order
will form an Arithmetic progression.
As the common difference
,same for three consecutive terms so this an AP.
Now accordingly we can put the AP terms.
Total number of seats 
Seats in the first row 
Seats in the last row 
Summation of
terms in AP
![S_n={\frac{n}{2}[2a+(n-1)d]}](https://tex.z-dn.net/?f=S_n%3D%7B%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%7D)
OR
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
Using the second equation.
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
![1560=\frac{n}{2}[23+81]](https://tex.z-dn.net/?f=1560%3D%5Cfrac%7Bn%7D%7B2%7D%5B23%2B81%5D)

So the number of rows (n) in the theater 
5(2.7)= 13.5
You just plug in 2.7 for x
