Using the information above, we can find our answer:

Our answer is
, or A.
Answer: I believe it is D
Why: Domain=x which gets rid of A, and C and because you cannot really now how many tickets you will sale (like B states certain numbers not the range of possibility) I think it’s D
Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

hence, measure of the third side is 6x + 1
Since there are 60 seconds in a minute multiply 8 by 60
The rate is 480 feet per minute.
