Answer:
Step-by-step explanation:
2,y,18,-54,162,...
This is a geometric sequence
Common ratio r = T2/T1 = T3/T2
y/2 = -54/18
Cross multiply
y(18) = 2(-54)
18y = - 108
y = -108/18
y = -6
Answer:
4 and 8
Step-by-step explanation:
You don't need the surface area to find the edge length of a cube. Length of edge = ∛volume
Cube 1:
Length of each edge = ∛64 = 4 in.
Area of each face = 4² = 16 in².
Surface area = 6×16 = 96 in².
Cube 2:
Length of each edge = ∛512 = 8 in
Area of each face = 8² = 64 in²
Surface area = 6×64 = 384 in²
So the surface area is in the ratio 1:4
