i don't know what the math is. i would like to try to help
Step-by-step explanation:
Answer:
The answer is 
Step-by-step explanation:
In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.
In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.

We divide each side by "W":

We simplify the "W" in the right side:

Finally, the solution for "L" is :

First, to be able to compare these two things, you have to either find the radius of Mercury or find the diameter of the moon. I choose finding the diameter of the moon because it seems easier.
Diameter=radius*2
Diameter=1736.5*2=3473
The moon has a diameter of 3473 km.
Since Mercury's diameter, 4878km, is greater than the Moon's diameter, 3473km, Mercury is larger.
Hope this helps!
A) first choice because for x=0 the y= 5 and for x=2 the y=3
