(2 + 2y - x) is equal to​

Answer 1

Answer:

k=4

Explain Step by step:

x,y,z- A.P

2y=x+2

(x+2y-2) (2y+2-x) (x+z-y) =(2x) (2z) y =4xyz

4xyz=kxyz

k=4

Answer 2

Step-by-step explanation:

Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force. By resolving force →F into two components : (i) F cosθ in the direction of displacement of the body. (ii) F sinθ in the perpendicular direction of displacement of the body.
