Answer:
Associative property
Step-by-step explanation:
This property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends (or the multiplicands).
eg. a+(b+c) is same as (a+b)+c
The lines intersected by a transversal must be parallel.
this is not a parallelogram .
the answer would be 4
because 120 divided by 30 is 4
