The answer is 2/3 I can't explain but I know the answer
To use the elimination method, you have to create variables that have the same coefficient, then you can eliminate them.
Answer:gcf is 12 .
12(2+7)
Step-by-step explanation:write gcf first then this ( and then think what is 24 times 12 which is the GCF which is 2 and think what is 84 divide 12 which is 7.Now put 12 ( 2+7)
Hope it helps :)
Given that
z = 3 cis(30°)
z = 3 (cos(30°) + i sin(30°))
by DeMoivre's theorem it follows that
z³ = 3³ (cos(3×30°) + i sin(3×30°))
z³ = 27 (cos(90°) + i sin(90°))
z³ = 27 (0 + i)
z³ = <u>0</u> + <u>27</u> i
