Which equation demonstrates the additive identity property? a. (7 + 4i) + (7- 4i) = 14 b. (7 + 4i) + 0 = 7 + 4i c. ( 7 + 4i) (1) = 7 + 4i d. (7 + 4i) + (-7- 4i) =0

we know that

Additive identity property:

If we add a real number to zero or add zero to a real number, then we get the same real number back.

The number zero is known as the identity element, or the additive identity.

For example: a+0 =a

we can see that adding gives same result

so, 0 is the additive identity here

Hence , option-BAnswer

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
