Product means to multiply 2 numbers and for this question its 9x4. The devided by 6 part is just divided from 6. so (9x4)/6
Hope this helped!
Answer:
Step-by-step explanation:
Measure of angle V = 180 - 62 - 36 = 82 degrees
So by the law of sines, 10/sin(82 deg) = w/sin(62 deg)
w = [10sin(62)]/sin(82)
from here just plug this into a calculator
The answer would be -9 -15n because you would be adding one to the -10 to the one and -9 and plus -2 and plus negative for any equals 15n
There are two ways to work this out: normal variables or using "imaginary" numbers.
Normal variables:
![(7+2i)(3-i)\\(7*3)+[7*(-i)]+(3*2i)+[2i*(-i)]\\21-7i+6i-2i^{2}\\\\21-i-2i^{2}](https://tex.z-dn.net/?f=%20%287%2B2i%29%283-i%29%5C%5C%287%2A3%29%2B%5B7%2A%28-i%29%5D%2B%283%2A2i%29%2B%5B2i%2A%28-i%29%5D%5C%5C21-7i%2B6i-2i%5E%7B2%7D%5C%5C%5C%5C21-i-2i%5E%7B2%7D)
Imaginary numbers:
Using the result from earlier:

Now since

, then the expression becomes:
