Answer:
see explanation
Step-by-step explanation:
Using De Moivre's theorem
Given
[ 4(cos15° + isin15° ) ]³, then
= 4³ [ cos(3 × 15°) + isin(3 × 15°) ]
= 64 (cos45° + isin45° )
= 64 ( + i )
= 64 ( (1 + i) )
= 32 (1 + i)
= 32 + 32 i
Divide it then subtract the left overs.
I think you don't have ALL the choices listed.

Answer:
x = 3
Step-by-step explanation:
Things to note:
- The line is going up and down
- The line is intersecting with the x axis and 3
Therefore, we can conclude the equation of the line is x = 3
J. 4y + 8
4(y + 2). <—— multiply 4 by what’s in the parentheses
4 • y = 4y
4 • 2 = 8
