Answer:

Step-by-step explanation:
The binomials are multiplied in the usual way, using FOIL or the distributive property:
(5 -2i)(3 -4i) = 15 -20i -6i +8i²
Since i² = -1, this becomes ...
= 15 -20i -6i -8 = 7 -26i
A. -f(1)=1,f(2)=2,f(n)=2f(n-1)f(n-2);n>2
Answer:

Step-by-step explanation:
The coordinate has the following polar form:

The image of the coordinate rotated counterclockwise 60° is:

Its equivalent form in rectangular coordinates is:


Answer:
6x+3
Step-by-step explanation:
(x+4)+(3x-2)+(2x+1)
=x+4+3x-2+2x+1
=x+4+3x-2+2x+1 --> Here I'm just bolding the variables. This makes it easier to combine like terms in the next line.
=6x+4-2+1
=6x+3
