Answer:
B,D
Step-by-step explanation:
The small number is always the bigger one in negatives because it is closer to 0 in a timeline
_-6_-5_-4_-3_-2_-1_0_1_2_3_4_5_6
21 fewer stars than three times a number h
21 - (3 x h)
What I understand is that if this are the three options that you put you should choose X2
The commutative property is when you are switching the order of the numbers/variables, and the associative property is when you switch the grouping. So for the first line, the answer would be the the associative property, the second line is the commutative property, and so on and so forth. Does this help you?
