Answer: (4-4i)+(3-2i) = 7-6i
Step-by-step explanation:
To add or subtract two complex numbers, just add or subtract the corresponding real and imaginary parts. For instance, the sum of 4 -4i and 3 - 2i is 7 -6i. The numbers in standard form will be a + bi, where a is the real part and bi is the imaginary part.
23, you have to round down. If it was 23.527 it would be 24.
The area of a circle is pi times radius^2
So if you use 3.14 x 16, it gives you approximately 50.264
