Answer: My bad if I butchered any answers. It was hard to read tbh
Step-by-step explanation:
D.) You can only factor out an x here. So you'd get: 
E.) You can factor out a 3x^2y to get: 
F.) You can factor out a 3xy to get: 
G.) You can factor out a -4ab to get: 
Answer:
B
Step-by-step explanation:
given the first 3 terms of the geometric sequence - 4, 20, - 100
with r =
=
= - 5
the n th term formula ( explicit formula ) is
=

here r = - 5 and
= - 4, hence
= - 4
with n ≥ 1
