Answer:

Step-by-step explanation:

Answer:8
Step-by-step explanation;Since you want to find the density but you already have the mass you do the inverse operation and divdie 56 by 7 and get 8.
If it is geometric then
if the terms are a,b,c,d then
b/a=c/b=d/c
so
-54/-81=-36/-54=-24/-36?
2/3=2/3=2/3
and that is the common ratio
it is geomertic and common ratio is 2/3
If you factored this the outcome would be,
(q+3)(3p^2-4)
The answer to this question is true
