Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)
Answer:
5
Step-by-step explanation:
evaluate f(4) by substituting x = 4 into f(x) and g(2) by substituting x = 2 into g(x)
f(4) = (3 × 4) - 3 = 12 - 3 = 9
g(2) = (2 × 2 ) = 4
f(4) - g(2) = 9 - 4 = 5
When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:

After this, we merely need to simplify the answer.


Simplifying 12/2 gives us the answer 6.
In a circle, the arc is two times the length of the angle.
EFG = 98°
98 x 2 = 196
Minor arc EG = 196°

Answer:
tan (A-B) = ± 4/3
Step-by-step explanation:
COS (A-B) = 3/5
COS² (A-B) = (3/5)² = 9/25 = 1 - sin² (A-B)
sin² (A-B) = 1 - 9/25 = 16/25
sin (A-B) = ± 4/5
tan (A-B) = sin (A-B) / cos (A-B) = (± 4/5) / (3/5) = ± 4/3
