A quartic polynomial has only 'x' as it's variable and has a leading coefficient of -7. It's linear term has a coefficient of 2, it has a constant of -3, it's quadratic term has a coefficient of -9 and it's cubic term has a coefficient of 12. What is the polynomial in standard form?

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.

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
