Answer:

Step-by-step explanation:
Evaluate all the arithmetic first, and then remember absolute value equations have two possible ways to go (+ and -).
You can see how I split them on the 3rd line, later demonstrating how the 2nd one is invalid.

Therefore, the solution is 
Answer:
247
Step-by-step explanation:
From the question given above, the following data were obtained:
nth term (Tₙ) = 5n – 3
Number of term (n) = 50
50th term (T₅₀) =?
The 50th term can be obtained as follow:
Tₙ = 5n – 3
T₅₀ = 5(50) – 3
T₅₀ = 250 – 3
T₅₀ = 247
Therefore, the 50th term is 247.
Answer:
2 units
Step-by-step explanation:
Given data
The points are (2, 3) and (2, 5)
x1= 2
y1= 3
x2= 2
y2= 5
substitute into the distance between two points formula
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-2)²+(5-3)²)
d=√(2)²)
d=√4
d= 2 units
Hence the length is 2 units
