Anya started solving for the volume of the pyramid using the steps below. V = one-third B h B = 12 (12) = 144 feet squared A square pyramid with a base of 12 feet by 12 feet and height of 15 feet. What is the final step in determining the volume of the pyramid?

it is c, trust i got your back lol

step-by-step explanation:

thats not a system of equations, that is a solution

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.
