You'll need to use parentheses here to convey this problem accurately to possible helpers. Unsure of whether you mean (9/2)k -3 or 9 / (2k-3).
I will assume that you mean:
9 4
------- = ---------
2k-3 k+1
Cross mult: 9k+9=8k-12, so k= -21.
If that's not what you expected, then try again to present the problem without ambiguities.
Whatever% of anything is just (whatever/100) * anything.
thus 29.5% of something, is just (29.5/100) * something, and the decimal form of 29.5% is just 29.5/100 or the quotient of 29.5÷100.

Answer:
C, D
Step-by-step explanation:
The equation factors as ...
(x -3)(x +3) = 0
The value will be zero when a factor is zero. That is, solutions are ...
x = 3 and x = -3 . . . . . matches choices C and D
