Can someone help wit that asap

A

Step-by-step explanation:

The important thing here is that for the quadratic formula to be able to be applied you need the equation to be equal to 0. Then in this case we know that once it is equal to 0 the coefficients have to be: a = 1, b = 3, c = 24

Only A satisfies both conditions

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

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.
