Question

1. which property justifies -25c + (6c + 3c) = (-25c + 6c) + 3c? associative distributive commutative identify

Explanation:

The associative property of addition states that for any real - numbers a, b, and c, a+(b + c)=(a + b)+c. In the expression - 25c+(6c + 3c)=(-25c + 6c)+3c, the grouping of the terms being added is changed, which is characteristic of the associative property. The distributive property involves multiplication over addition (a(b + c)=ab+ac), the commutative property involves changing the order of addition (a + b=b + a), and the identity property involves adding 0 (a+0 = a).

Answer:

associative
