Solve 9 (3)x =243 for x

x=3

Step-by-step explanation:

Do you mean 9(3)^x=243? Then the solution is:

9(3)^x=243

(3)^x=27

log₃((3)^x)=log₃(27)

x=3

Therefore, x=3

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.
