By definition, skew lines are a pair of lines that are not parallel but do not intersect each other either. Hence, the conclusion would be, the lines are non-coplanar. An example would two random lines drawn in the x and y axes in a cartesian plane, respectively.

Sample Response:

Skew lines are noncoplanar and do not intersect. Line a lies in plane Q and line b lies in plane R, so the lines are not coplanar. No other plane can be drawn through the lines, so they are not parallel. So, a and b are skew.

9) The area of Vaughn's dog pen is 341square feet

Wittaler [7]

Answer:

15.5 feet

Step-by-step explanation:

Since length * width = area, we can plug in for the values we are given

We'll set x = width

So 22 * x = 341

22x = 341

x = 15.5

We can check this by multiplying 22 and 15.5 together which gives us 341
