factorising the first denominator
x²-2x-3 = x² -3x+x-3 = (x+1)(x-3)
(a) 
finding LCD
(b) LCD of (x-3)(x+1) and (x-3) is (x-3)(x+1)
(c)

(d)



Answer:
The answer is C
Step-by-step explanation:
Let X and Y be two proportional quantities and let K be constant.
Y=KX so Y/X=K
So for Equation number 1 we have 4y=3x and we will fill it in for 4/3=K
solving to get 1.33...
Now repeat this for the rest to complete the chart
1- 1.33...
2. 1.6
3- 1.33...
4- 0.625
Now we can see that 1 and 3 are the same, so that's how you get your answer, hope this helps!
