Answer:
We don't know that they skew but if Q and R are the same length then they aren't. But if Q and R are different lengths then they are skew. It would help to post a picture.

Answer:
the new ratio of white, red and blue balls is 6:2:1
Step-by-step explanation:
The computation of the new ratio is shown below:
If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls
Now if 10 white and 10 blue balls would be eliminated
So there is 30 white, 10 red, 5 blue bals
Also
30 = 5 × 6
And,
10 = 5 × 2
so the new ratio of white, red and blue balls is 6:2:1
Answer: 38
Step-by-step explanation:
14 - 2xy
(substitute x and y)
14 - 2 (-6) (2)
14 + 24
38
Answer:
The range in shelter A is 22, and the range in shelter B is 18.
Step-by-step explanation:
The range is the largest value minus the smallest value.
For shelter A, the range is 30 − 8 = 22.
For shelter B, the range is 28 − 10 = 18.
Answer:
And on this case the samllest possible value would be 1
Step-by-step explanation:
For this case we have the following expression:
And we can rewrite this expression like this:
For this case is important to remember the following property from algebra:
On this case we can see that 
So then 
So then we can simplify all the expression and we got this:
And on this case the samllest possible value would be 1
