The variables a, b, and c represent polynomials where a = x², b = 3x + 2, and c = x - 3. what is ab - c in simplest form?
3x3 + 2x2-x+3
3x3 + 2x2-x-3
3x3 + x2 - 6x + 9
3x3 + x2 + 6x -9

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

49/6 is going to equal 8 1/6
