Answer:
C.
Step-by-step explanation:
A line is straight, and a segment is a part of a line.
A and D and lines because they have the arrows on the side, meaning they keep going and are not a segment.
B is not a line, it curves.
So that leaves C to be the answer because it is the only straight one with no arrows.
Answer:
Length of third side is: 
Step-by-step explanation:
Perimeter of triangle = 
Length of side 1= 
Length of side 2= 
We need to find length of third side.
The formula used is: 
Putting values and finding length of third side.

So, Length of third side is: 
Using the law of sins:
B =sin^−1((sin(A)⋅a)/b) = sin^−1((sin(65)⋅110)/155)=40.03 degrees
B= 40.03 degrees (round as needed)
Slope is rise/run
to find it we do (y1-y2)/(x1-x2)
y1 means the 1st y and y2 means the second y
in (x,y) form
y1=4
y2=4
x1=10
x2=7
(4-4)/(10-7)=0/3=0
slope is 0
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
