make u the subject in x =\(\frac{2u-3}{3u + 2}\)
u = \(\frac{2x + 3}{3x - 2}\)
u = \(\frac{2x - 3}{3x - 2}\)
u = \(\frac{2x + 3}{2 - 3x}\)
u = \(\frac{2x + 3}{3x + 2}\)
Correct answer is C
x =\(\frac{2u-3}{3u + 2}\)
cross multiply
x(3u + 2) = 2u - 3
3ux + 2x = 2u - 3
collect like terms of u
2x + 3 = 2u - 3ux
\(\frac{2x + 3}{2 - 3x}\) = u

Correct answer is A
In a polygon with n sides, the sum of the angles =
(n - 2)180, where n = the number of sides.
In our problem, n = k.
So, we have:
(3k - 10)90 = (k - 2)180
270k - 900 = 180k - 360
Simplifying:
90k = 540
k = 6. So, we have a regular hexagon.
Now, each exterior angle = 360/n
We have: 360/6 = 60
Conclusion: Each exterior angle is 60 degrees.
