the additive inverse of non complex 9 is -9 .
<u>Step-by-step explanation:</u>
Complex number is said to be the sum of whole numbers and imaginary numbers.The additive inverse of the any number is the changing the sign of the number. That is instead –ve sign is positive and vice versa.
Additive Inverse of Complex Numbers:
Let take the complex numbers
and its inverse be 
Step 1: Now add the Z and Z-1, we get

Step 2: Combine Like term, we get

Step 3: By using zero product property, we can equating as
and 
and 
Thus, the additive inverse of the complex numbers
.
Now, additive inverse of
=
.
Therefore , the additive inverse of non complex 9 is -9 .
Answer:
B
Step-by-step explanation:
The value of the polynomial for x = 3 is the value of P(3)
P(3) = 2(3)³ - 7(3)² + 7(3) - 12 = 54 - 63 + 21 - 12 = 0 → B
If you were to add these both you would get 162
62+100=162
