Which property is shown? –7 + 24 = 24 + (–7) a. associative property b. distributive property c. opposite of a sum property d. commutative property

This is the commutative property. This is because the commutative property just moves stuff around for example a+b = b+a, is the commutative property. The associative property is a+(b+c) = (a+b)+c, the distributive property is a(b+c) = ab+ac, and the opposite of a sum property is -(a+b) = (-a)+(-b).
