=5x−10

Step-by-step explanation: hope this help

Let's simplify step-by-step.

3(3x−4)−2(2x−1)

Distribute:

=(3)(3x)+(3)(−4)+(−2)(2x)+(−2)(−1)

=9x+−12+−4x+2

Combine Like Terms:

=9x+−12+−4x+2

=(9x+−4x)+(−12+2)

=5x+−10

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
