A. identity property of multiplication
B. identity property of addition
C. distributive property
D. inverse property of multiplication

Answer 1

Do you know what each of these properties mean?

Answer 2

No

Answer 3

Okay, I'll give you the definition:

Identity property of multiplication: This property says that a number does not change when that number is multiplied by 1. (example: 2 * 1 = 1 or 5678493 * 1 = 5678493)

Distributive Property: This is a property that is used to multiply a single term and two or more terms inside a set of parentheses. (example: 3(5 + x) = 15 + 3x you multiply 3 by both terms/numbers/variables inside of the parentheses)

Inverse Property of Multiplication: This property says that if you multiply a number by its reciprocal (multiplicative inverse) the product is 1. (example: 1/4 * 4 = 1 or 4 * 1/4 = 1)

The Identity Property of Addition: This property says that zero added to any number is the number itself. (example: 3 + 0 = 3 or 5 + 0 = 5)
