f(x) = (2x-3)(x+6)(5x+6) has zeros at x = -6, x = -6/-5, and x = 3/2. what is the sign of f on the interval -6 < x < -6/-5?

1010: 3030

is it i think

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.

i think its a.

hope this
