Find the value of x for which a is invertible. X-1 x^2 x^4 chegg.

a 10 percent increase

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

you can't solve x because it is 2 linear equation and you only have one equation

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.
