Planes t and x are parallel. plane t contains line a. plane x contains line b. which best explains the relationship between lines a and b?

I found the missing choices. These are:

They are skew and will never intersect.
They are parallel and will never intersect.
They are perpendicular and will intersect.
They will intersect at two points.

My  They are skew and will never intersect.

Lines a and b are skew lines because they are not parallel and they do not intersect. The reason that they do not intersect is because each line is in a parallel plane. Parallel means going to the same direction but neither converging nor diverging.

The quotient of three and a number:
=> Which operation is needed, The answer is letter d. Division.
Quotient is the answer of the equation that uses division as operation.
For Addition the answer is called sum.
For subtraction the answer is called as difference
and for multiplication the answer is called product.
Since, the equation is the quotient of three and a number = 3 / n, where N is used as an unknown number. Thus, it uses division.
