In the accompanying figure, ΔABC has coordinates A(0,3), B(7,3), and C(7,7). What is the area of ΔABC in square units? A. 15 units²
B. 24.5 units²
C. 14 units²
D. 28 units²

2,600 divided by 80 = 32.5

(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.

c(x)= 6x + 3
