Answer:
Multiplying a complex number by a real number
(x + yi) u = xu + yu i. In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0.
binomial methods
Complex numbers use binomial methods of multiplication because unlike real numbers, imaginary numbers have two components.
So probably A. I sorry, but I need more information. Hope this helps

Answer:

Step-by-step explanation:
Given
Peter hits
Mary hits
Required
The probability that Mary wins
From the question, we understand that Peter throws the first.
If Mary is to win, then Peter has to lose his throw
Using the complement rule, the probability that Peter misses is:

So, the probability that Mary wins is:

This gives:

Answer: Im pretty sure it would be 67, find area of each side then add
Answer:
<h2>|-4.5| = 4.5</h2>
Step-by-step explanation:
|a| = a for a ≥ 0
|a| = -a for a < 0
therefore
|-4.5| = -(-4.5) = 4.5
In order from left to right:
D, C, A, B
