Use the order of operations to find the value of the following expression 3-4(-2-4)

27

Step-by-step explanation:

By the order of operations, we should first calculate the expression in the parentheses:

= 3 - 4 (- 6)

Next, we calculate the expression being multiplied:

= 3 + 24

Lastly, we add the two terms:

= 27

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.
