Answer:
-4, -2, 2, 8
Step-by-step explanation:
The first four terms will be found by evaluating the expression for values of n that are 1, 2, 3, 4. Evaluating for n=1 is sufficient to determine the correct answer choice:
n(n -1) -4
1(1 -1) -4 = -4 . . . . matches the third choice
You can cross multiply fractions only if there is an "=" sign in the middle of the two fractions.
The domain is (-∞,∞)
the range is (−∞,2]

Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is
of the total seats, we want to find the total number of seats so,
120 seats = 
We know that a whole fraction sums to 1 so for example 
120 seats = 
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only
of the total number of seats then the total number of seats is 600
