fourth degree trinomial.

Step-by-step explanation:

we have

Classify the polynomial

Remember that

Polynomials can be classified two different ways - by the number of terms and by their degree

1. Number of terms.

In this problem we have tree terms . so is a trinomial

2. Degree.

The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

In this problem the highest exponent is the so this is a fourth degree trinomial.

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
