Answer:
Step-by-step explanation:
n^2-7n is n(n-7). So n(n-7) = 0. We know n can be zero because 0* anything is 0. It could also be 7 because we are looking to multiply by 0. So to get a zero in the parentheses. you would do 0+7. Which is obviously, 7
The first and only stop of the flight can be Boise, Omaha or Chicago. This means there are 3 possibilities where to stop. From thee the flight connects to New York City, either to La Guardia or to JFK Airport.

Or in other words: There are two airports where the flight can arrive and for each of them there are three possible routes. So, in total there are 2*3=6 possible routes.
V = PI x r^2 x h/3
11^2 = 121
121 * 84 = 10164
answer is 10164PI units^3
answer is B
