Step-by-step explanation:
7-4x+6=10-4x+2
7+6-4x=10-2-4x
13-4x=8-4x
-4x+4x=8-13
x=-5
The correct value of (3cis(pi/6))³ is 27i.
<h3>What is Complex Number?</h3>
Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra.
Given the complex number in polar coordinate expressed as
z = r(cos∅+isin∅)
zⁿ = {r(cos∅+isin∅)}ⁿ
According to DeMoivre’s Theorem;
zⁿ = rⁿ(cosn∅+isinn∅)
Given the complex number;
(3cis(pi/6))³
= {3(cosπ/6 + isinπ/6)}³
Using DeMoivre’s Theorem;
= 3³(cos3π/6 + isin3π/6)
= 3³(cosπ/2 + isinπ/2)
= 3³(0 + i(1))
= 27i
Thus, the correct value of (3cis(pi/6))³ is 27i.

Answer:
R = 37 | S = 106
Step-by-step explanation:
Because of the triangle it is both the bottom angles will have the same measurement. Subtract both of their measurements from 180 (The total degrees). To get the answer for s. Which is 106
