Answer:
The given expression is:
-(1)/(9)(13x)
We can use the commutative property of multiplication to rearrange the order of the factors:
-(1)/(13x)(9)
Now, we can use the associative property of multiplication to group the factors in any way we want:
-(1/13)(1/x)(1/9)
This is the simplified expression using the commutative and associative properties of multiplication.
