He has 12 marbles.
There you go
Hi,
First we must go back to the formula of the Area of a 2d figure which is L*W or Length times the Width. So, we could divide 64 by 16.
64/16 = 4
The answer is 4.
Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero

only when the numerator equals 0 (the denominator cannot ever be zero):

and that happens only for x=4
The given equation is:

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

From first equation, we can write t =x/5. Using this value in second equation, we get:

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
