Which equation shows the Identity Property of Multiplication?

A. a x 1

B. (a + b) + 3 = a + (3 + b)

C. a (b + c) = ab + ac

D. a + a + a = 3 x a

A. a * 1

Step-by-step explanation:

The identity property of multiplication simply states that a number equals itself when multiplied by 1.

a * 1 is the identity property of multiplication.

(a + b) + 3 = a + (3 + b) is associative property.

a (b + c) = ab + ac is expansion.

a + a + a = 3 x a is factoring of like terms.
