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)

U didn’t give us the options soooo uhhhh C
Surface area = area of the square + 4 times area of one triangle
= 7*7 + 4(1/2 * 7 *14)
= 49 + 4*49 = 245 sq ins
