120/5 = 24
so 20 + 22 +24 +26 +28 = 120
5th number = 28
<span>They are both functions of the cube of the radius or even the cube of the diameter for that matter, since one is a linear function of the other.
V=(4/3) pi r^3
If you do volumes of both, the (4/3) and the pi cancel
Do ratios of r^3 Thats just an example</span>
Answer:what's is the question
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
This is the difference of perfect squares, which follows a pattern of
(A+B)(A-B)
We have 64, which is 8-squared,
we have A squared, which is A squared ( :/ )
we have 81, which is 9-squared, and
we have B-squared, which is B squared.
We can factor this then following the pattern into:
(8A+9B)(8A-9B)
Choice B only matches one of our binomials.
