answer is 12.26%
answer is B
Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

Which means that option E is correct.
The <em>volume of a cube</em> of side length l is given by:

For Cube A, the volume is of 9 cubic inches, hence:

![l_a = \sqrt[3]{9}](https://tex.z-dn.net/?f=l_a%20%3D%20%5Csqrt%5B3%5D%7B9%7D)


For Cube B, the volume is of 5 cubic inches, hence:

![l_b = \sqrt[3]{5}](https://tex.z-dn.net/?f=l_b%20%3D%20%5Csqrt%5B3%5D%7B5%7D)

Then, the ratio is:

15 + 20p = c ( this is the answer )
fifteen plus twenty times the number of parts equals the total cost.
Answer:
Option B
27x³ – 108x² + 144x – 64
Step-by-step explanation:
(3x – 4)³
(3x – 4) × (3x – 4) × (3x – 4)
(9x² – 12x – 12x + 16) × (3x – 4)
(9x² – 24x + 16) × (3x – 4)
27x³ – 36x² – 72x² + 96x + 48x – 64
27x³ – 108x² + 144x – 64
Thus, The answer is 27x³ – 108x² + 144x – 64
