2) 
Step-by-step explanation:
In mathematics there are rules related to complex numbers, specifically in the case of addition and multiplication:
<u>Addition:
</u>
If we have two complex numbers written in their binomial form, the sum of both will be a complex number whose real part is the sum of the real parts and whose imaginary part is the sum of the imaginary parts (similarly as the sum of two binomials).
For example, the addition of these two binomials is:

Similarly, the addition of two complex numbers is:
Here the complex part is the number with the 
<u>Multiplication:
</u>
If we have two complex numbers written in their binomial form, the multiplication of both will be the same as the multiplication (product) of two binomials, taking into account that
.
For example, the multiplication of these two binomials is:

Similarly, the multiplication of two complex numbers is:
Answer:
He can watch 8 movies
Step-by-step explanation:
100-40.66=59.34
6.71 x 8 = 53.68
therefore the most amount of movies he can watch is 8
Answer:
Not enough data
Step-by-step explanation:
5 = 1/3
So divide each side by 5
we get
1 = 1 / 15
Each roll needs 1 / 15 cups of flour
Juice:water is 1:3 so insert water and leave the juice blank. __:36. You can set these up as fractions: 1/3 = x/36. Cross multiply: 1 X 36= 36 and 36 divided by 3 is 12. Another way to figure this out is this: 3 divided by 3 is 1 (1:3) so 36 divided by 3 equals 12 (12:36) The answer is 12 cups of juice either way
