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
Step-by-step explanation:
Answer:
B. (12-6) n - 50
Step-by-step explanation:
Given that:
Cost of making hat = $6 per hat
Selling price = $12 per hat
Advert cost = $50
Number of hats made = n
The profit or money raised from the sales of hat:
Total Revenue from sales - total cost of production - advert cost
Total Revenue from sales = ($12 * n) = $12n
Total cost of production = ($6 * n) = $6n
Advert cost = $50
Hence,
12n - (6n + 50)
12n - 6n - 50
(12 - 6)n - 50
Answer:
(x-4)(x+10)
Step-by-step explanation:
A = 2
b = -5
c = 6
The coefficients are 2 and -5
The constant is 6
