Answer:
c
Step-by-step explanation:
They spent 5839 on electrical appliances and 6659 on furniture
FIRST. find the factors:
X=-5 --> (X + 5) = 0
x = 1--> (X - 1) = 0
x =3 --> (x - 3) = 0
3
NEXT, multiply all the factors:
(x + 5) (x - 1) (x - 3) = 0
-> X3 + x2 - 17x +15 = 0
-> f(x) = x3 + x2 - 17x +15 or
y=x3 + x2
17x + 15
This sequence is not a geometric.
It is because, common ratio = 6/3 = 2
9/6 = 1.5
As the ratio's are not same, it is not a G.P
Hope this helps!
