The expression that shows the best use of the associative and commutative properties is
. The correct option is C. ![[\frac{3}{4}+(-\frac{2}{4})]+[9 +2+(-5)]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%7D%7B4%7D%2B%28-%5Cfrac%7B2%7D%7B4%7D%29%5D%2B%5B9%20%2B2%2B%28-5%29%5D)
<h3>Associative and Commutative properties </h3>
From the question, we are to determine the expression that shows the best use of the associative and commutative properties
The given expression is

To easier simplify the expression, we can group the fractions together and group the whole numbers together
That is,
![[\frac{3}{4}+(-\frac{2}{4})]+[9 +2+(-5)]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%7D%7B4%7D%2B%28-%5Cfrac%7B2%7D%7B4%7D%29%5D%2B%5B9%20%2B2%2B%28-5%29%5D)
Hence, the expression that shows the best use of the associative and commutative properties is
. The correct option is C. ![[\frac{3}{4}+(-\frac{2}{4})]+[9 +2+(-5)]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%7D%7B4%7D%2B%28-%5Cfrac%7B2%7D%7B4%7D%29%5D%2B%5B9%20%2B2%2B%28-5%29%5D)

Answer:

Step-by-step explanation:
we know that
The volume of a cube is equal to

where
s is the side length of the cube
we have

substitute in the formula


Remember the power rule
----> multiply the exponents
so

B is the one in standard form
The answer is 178.80 so maybe B is a typo
