To figure this equation out, you'll have to divide 39 by 52% (0,52)
39 / 0.52 = 75
39 is 52% of 75 is your answer.
Hope this helps!
We can take prime numbers so they don't have a common factor other than 1.
3, and 5.
So we have to list the multiples to find the LCM
3: 3, 6, 9, 12,
15, 18
5: 5, 10,
15, 20, 25
15 is the LCM of 3 and 5
So, you can notice that if two numbers, lets call them a and b, have no common factor, then

is the LCM.
Hope that helped :)
Step-by-step explanation:
That is my answer, luckily I did the test
This is a vertical parabola, because (x-1)².
Vertex of the parabola (1,1).
So line symmetry is x=1.
