Answer:not true
Step-by-step explanation:
To say not true we need only one example so we can take x as -5
[-5]= [-5+1]
5 not equal with 4
Option B:
A ray has two endpoints and extends infinitely in both directions.
Solution:
Option A: Two lines that intersect are called skew lines.
It is false because,
Two lines are said to be skew lines if they do not intersect and do not lie in the same plane.
Option B: A ray has two endpoints and extends infinitely in both directions.
It is false because,
A ray has one endpoint and extends infinitely in one direction.
Option C: A line is a set of points that extends infinitely in both directions.
It is false true.
A line is a set of points that extends infinitely in both directions.
Option D: Two lines in the same plane are said to be perpendicular if they never intersect.
It is false because,
Two lines are said to be perpendicular if they are intersect.
Hence Option B is true. A line is a set of points that extends infinitely in both directions.

Answer:
5.14
Step-by-step explanation:
The way i solved this was i found the length of the line by taking the 2 (Width and also "A") and the 7 (The height and also "B"), squared both of them and added them together. Then found the square root. Sense i suck at explaining things this is what the equation should have looked like. 
÷ 2. (Side wait for someone else to answer because i'm 70% sure this is right.
