throw the computer

step-by-step explanation:

i think the answer is true

step-by-step explanation:

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.

we are given dimensions of the sketch :

length = 12 inches.

width = 18 inches.

given scale factor = 0.2.

the actual dimensions of the mural would be: the sketch dimensions divide by scale factor.

(because the mural would be larger than the sketch dimensions).

we need to find the actualy length of the mural.

therefore,

the length of the mural = 12 inches ÷ 0.2 = 60 inches.
