The expression (2 x 7) x 3 represents the number of times Brandon went to the beach each week during 3 months. Which property is applied to write the equivalent expression 2 x (7x 3)? A. Distributive Property B. Commutative Property of Addition C. Associative Property of Multiplication D. Identity Property of Multiplication

B. Distributive property

Step-by-step explanation:

Because (2 times 7) times 3 is the same as 2 times (7 times 3)

The numbers are just put different, and makes a different answer.

So, just because the answers are the same, doesn't make them commutative property,

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

i dont have an answer
