Answer:
The length of segment TR with T(-4,5) and R(2, -1) is 8.49
Step-by-step explanation:
We need to find the length of segment TR with T(-4,5) and R(2, -1)
The length of segment can be found using distance formula.
The distance formula is: 
Putting values and finding length
We have: 

We found Distance = 8.49
So, The length of segment TR with T(-4,5) and R(2, -1) is 8.49.
Answer:
1. He ignored 4 on the first line
2. 9 - 2x
Step-by-step explanation:
4 - 2(x + 5)
4 - 2x + 5
9 - 2x
5x - 5x + 3x - 3x = 0
****since there is one positive and one negative of both 5x and 3x everything would cancel and the equation would equal 0
Answer: |-10| < |11|
So choice C. is right.
hope this helps!
