Answer:
B: -6+2i
Step-by-step explanation:
- 3i + (-6 - i) = ⇒ open parenthesis
- 3i - 6 - i = ⇒ simplify
- -6 + 2i ⇒ answer in standard form of a+bi
Answer:
50
Step-by-step explanation:
- 8i = √-64
8i + 6
- -4i = -√-16
-4i + 3
[8i + 6][-4i + 3] → FOIL
>> -32i² + [24i - 24i] + 18
↑ ↑
-1 0
>>> 32 + 18 = 50
Information on Imaginary Numbers
√-1 = i
-1 = i²
-i = i³
1 = i⁴ [And every other exponent that is a multiple of 4; this cycle then repeats itself every time you go up one number at a time]

Answer:
The Current Insurance cost = $685.43
Step-by-step explanation:
Given that Dan pays £714.73 a year on his car insurance.
Reduced Percentage = 4.1%
so
Reduced Amount = 4.1% × 714.73
= [4.1 / 100] × [714.73]
= 0.041 × 714.73
= $29.30
The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.
so
Current Insurance cost = 714.73 - 29.30
= $685.43
Therefore, the Current Insurance cost = $685.43
