Answer: Associative Property
Step-by-step explanation:
- The opposite of sum property says the opposite of a sum of real numbers or addends is equal to the sum of the opposites.
i.e. [tex]-a+(-b)=-(a+b)[/tex] where a and b are any arbitrary numbers.
The given expression : [tex](-3.4+(-9.2))+(-5.6)=-(3.4+9.2)+(-5.6)[/tex]
Here, [tex](-3.4+(-9.2))=-(3.4+9.2)[/tex] by using the opposite of sum property.
Hence, the correct answer is "opposite of sum property"
