Answer:
- 14 + 18i
Step-by-step explanation:
Note that i² = ( )² = - 1
Given
4i(- i + 3) - 3(6 - 21) ← distribute both parenthesis
= - 4i² + 12i - 18 + 6i
= - 4(- 1) - 18 + 18i
= 4 - 18 + 18i
= - 14 + 18i

Step-by-step explanation:
Answer:
x = 90° or π/2 rad
Step-by-step explanation:
4+ 2 sin x=14-8 sin x
2 sin x + 8 sin x = 14 - 4
10 sin x = 10
sin x = 1
Using a calculator
x = sin1
x = 90° or π/2 rad
