Answer:

The volume is 128cm^3
Step-by-step explanation:
Given


Required
Determine an expression for its volume
Find the volume
Volume of a cube is:

Where x represents the length of a side
So, volume of 2 cubes would be:


Solving (b): Volume when x = 4
Substitute 3 for x in 



<em>Hence, the volume is 128cm^3</em>
Answer:
9 = n
Step-by-step explanation:
12 = 6(n – 7)
Divide by 6 on both sides
12/6 = 6/6(n – 7)
2 = n-7
Add 7 to each side
2+7 = n-7+7
9 = n
Answer:
k = 2a = 10
Step-by-step explanation:
If
x² / 25 − y² / 56 = 1
we know that
a² = 25 ⇒ a = 5
b² = 256 ⇒ b = √256
The equation of the hyperbola defined by |FP − PG| = k can be written as follows:
|FP − PG| = 2*a
then
2*a = 2*5 = 10
