Answer: 17 easy how could you not get it but yea thats that
Step-by-step explanation:
Two hundred Eighty One Point One Twenty Five Thousandths.
It is okay to take the inverse of both side given that you remember to exclude the value that make the denominator zero which is in this case r=-1
The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS
Hope this helps you with your questions.
