use the properties of complex numbers to simplify (8 + 6i) + (9 − 6i). (1 point)
17 − 12i
17
17 + i
17 + 12i

Explanation:

Step1: Combine real parts

Add the real parts \(8\) and \(9\): \(8 + 9 = 17\)

Step2: Combine imaginary parts

Add the imaginary parts \(6i\) and \(-6i\): \(6i + (-6i) = 0\)

Step3: Sum the results

Add the results from Step1 and Step2: \(17 + 0 = 17\)

Answer:

17 (corresponding to the option "17")
