Answer:
the recursive formula is
an=an-1 +d
an would be the n-th term witch is 8, d would be the difference witch is 5
an= (33) +5 an-1 would be the previous term (7th) I added five to the terms until I got to the 7th term
the 8th term is 38
the explicit formula is
an= a1 + (n-1)d
an= -2 + (53-1) -3
an= -2 + -156
an= -158
sorry but I haven't used this formula before but I did try my best using it

Answer:
(x - 9)(x - 9)
Step-by-step explanation:
<em>Hey there!</em>
Well to factor,
x^2-18x+81
we need to figure out what times what equal 81 and adds together to get -18.
-9*-9 = 81
-9 + -9 = -18
x*x = x^2
Factored - (x - 9)(x - 9)
