X would be -3, -2*12 then divide 8
It's the first one. That is a perfect square polynomial, which, when factored, will give you the same binomial twice, or multiplicity 2. It will factor to

, where the vertex (h, k), is (-9, 0).

Answer:
#1 is 10
# 2 is
6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The (Mean) = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4
= 16/10 = 1 6/10
The (MAD) = 1 6/10
#3 Groups A & B
#4 sorry I can’t figure this out but I did 1/2/3
