Answer:
The value of the expression at x=5 is 10
Step-by-step explanation:
The given expression is 
Let us simplify this expression.
Distribute -2 over the parentheses, we get

Now, substitute x = 5, we get

On simplifying, we get

The value of the expression at x=5 is 10
For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
