Perform the operation $( 3 - 4 i ) + ( 6 + 6 i )$ and write the result in standard form.
A) $9 + 2 i$
B) $9 - 2 i$
C) $9 i + 10$
D) $9 + 10 i$
E) $9 i - 2$

To perform the operation, add the real parts and the imaginary parts separately: $3 + 6 = 9$ for the real part and $-4i + 6i = 2i$ for the imaginary part. Thus, the result in standard form is $9 + 2i$.

Perform the Operation (3−4i)+(6+6i)( 3 - 4 i ) + ( 6 + 6 i )(3−4i)+(6+6i)

Perform the Operation $( 3 - 4 i ) + ( 6 + 6 i )$
