−1 + 10i
1 + 6i
1 + 10i
The given expression simplified can be written as -1 + 6i. which is the correct answer that would be an option (A).
A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib,
where a, and b are real numbers and i is an imaginary number.
To simplify the expression (3 + 8i) − (4 + 2i), we need to subtract the two complex numbers. To do this, we subtract the real parts and the imaginary parts separately.
The real part of the first complex number is 3, and the real part of the second complex number is 4.
Subtracting these gives us -1.
The imaginary part of the first complex number is 8, and the imaginary part of the second complex number is 2.
Subtracting these gives us 6. Therefore, the simplified expression is (-1) + (6i) = -1 + 6i.
Therefore, the correct answer is: -1 + 6i.

Answer:
-1+6i
Step-by-step explanation:
(3+8i)-(4+2i)
3+8i-4-2i
3-4+8i-2i
-1+6i
Higher = warmer
Lower = colder
Therefore, what temperature is 10 degrees higher than -22 degrees Celsius is -12 degrees celsius
