We have this following information
30-seconds ad = $146000
The manufacturer wants to use one slot of 30-second per segment
Total segment = 20 segment
Total campaign cost = 20×146000 = $2,920,000
Answer:
a) 6
Step-by-step explanation:
Expanding the polynomial using the formula:

Also

I think you mean 
We can deduce that this term will be located somewhere in the middle. So I will calculate
.
For 

Note that we actually don't need to do all this process. There's no necessity to calculate the binomial, just 
For 

I believe the answer is 27/30
For this case we have the following expression:

The first step is to solve the quadratic term.
We have then:

Then, the second step is to subtract both resulting numbers:

We observe that the result obtained is a negative number.
Answer:
The result of the expression is given by:
