Using the above expression, verify the equivalence of your combined expression (8a) and the given expression (3a + 5a) by evaluating both at the given value of a:
a=2
They are both equal to

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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
