1. subtract (7 – 19i) from (–6 + 12i). a. –13 – 31i b. –13 + 31i c. 13 – 31i d. 13 + 31i

C. 13 – 31i

Step-by-step explanation:

(7 – 19i) from (–6 + 12i)

That means

-6 +12i -  (7 – 19i)

Distribute the minus sign

-6 +12i -  7 + 19i

-6-7 +12i +19i

-13 +31i

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
