Answer:
41 + 11i
Step-by-step explanation:
Note that i² = - 1
Given
(3 - 5i)(2 + 7i) ← expand using FOIL
= 6 + 21i - 10i - 35i² ← collect like terms
= 6 + 11i + 35
= 41 + 11i
Answer:
17b - 2
Step-by-step explanation:
5b - 5 - 12b - 7
Say bye to the 12b, and add 12 to it and the 5.
5b + 12 = 17b
17b - 5 - 7
Add 5 to the 5 and the -7.
-7 + 5 = -2.
Now you have 17b - 2. You can’t go farther, so there’s your answer.
