Final answer:
The value of z² + 6 cannot be determined based on the given information.
Step-by-step explanation:
To find the value of z² + 6, we need to substitute the value of z from the given equation. The given equation states that 22 - 6 = 19, which is not correct. So, the equation is false. Therefore, we cannot determine the value of z² + 6 based on the given information. The answer is D) S.
