You made the choice to choose the letter A, a second time.
Answer:
4
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = (
, 
)
AB = 
+ 
=

= 4
Answer:
100 Joules
Step-by-step explanation:
We use the definition of Work as the force applied multiplied by the distance the object was moved. In our case the force exerted is 50 N, over a distance of 2 meters, therefore:
Work = F * d = 50 N * 2 m = 100 N*m = 100 Joules
The SI unit for Newton times meter is called "Joule".
The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
