Multiply everything in the parentheses by the 4
this equals 4x + 2
since one term has a variable and ine doesnt, they cannot be combined.
Answer:
Re(z)=12.1,
Im(z)=14.
Step-by-step explanation:
Re(z) is the real part of the complex number. It always stands without i (imaginary unit), thus,
Re(z)=12.1.
Im(z) is the imaginary part of the complex number. It always stand with imaginary unit i. Hence,
Im(z)=14.
The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
