Question

what property is this? (n + 13) + 4 = n + (13 + 4) distributive property commutative property associative property additive identity

Explanation:

The associative property of addition states that for any real numbers a, b, and c, (a + b) + c=a+(b + c). In the given equation (n + 13)+4=n+(13 + 4), the grouping of the numbers being added changes while the sum remains the same, which is characteristic of the associative property.

Answer:

C. Associative Property
