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:
8+11=19 but if you add 21+19+12+5=57.
Check the picture, notice the domain in red.
recall that the domain is the values for the x-coordinate, whilst the range is the values for the y-coordinate.
That is way too much questions for one sitting. If you really struggle that much, download this app called photomath. You take a picture of one of the questions and then it instantly solves it and shows the work so you know how to do it.
For 16-25 however, you would need to rewrite your questions on a blank piece of paper with the variables substituted in. So let's say:
a + b² - (c-2).
You would need to rewrite it as the following in order for the app to solve it.
12 + 9² - (4 -2)
Answer:
x = 95°
Step-by-step explanation:
x and 95 are vertical angles and congruent, thus
x = 95°
