Question

Which expression results from applying the Identity Property of Multiplication to
4c + 2c + c + 5 to get an equivalent expression?

Answer 1

The identity property of multiplication states that the product of 1 and any number or variable is the number or variable itself.
4c + 2c + c + 5

Its either gonna be :
(4c + 2c + c + 5) * 1 = 4c + 2c + c + 5
or
(7c + 5) * 1 = 7c + 5
