Perform the indicated operation. Write the result in standard form.
-$$( + 4 i ) - ( + 5 i ) + ( 8 + 8 i )$$
A) $17 + 17 \mathrm { i }$
B) $+ 17 i$
C) $+ 7 i$
D) $- 15 - 9 i$

The operation simplifies to $4i - 5i + 8 + 8i = 8 + 7i$, which is not listed, indicating a possible mistake in the options or interpretation. However, based on the closest match principle, option C, $+ 7 i$, is the correct choice for the imaginary part, assuming a typographical error in the options.

Perform the Indicated Operation (+4i)−(+5i)+(8+8i)( + 4 i ) - ( + 5 i ) + ( 8 + 8 i )(+4i)−(+5i)+(8+8i)

Perform the Indicated Operation $( + 4 i ) - ( + 5 i ) + ( 8 + 8 i )$
