What is area? how is the mass of a body? Write its si unit.
​

The total quantity of matter contained in an object is called its mass.

It is scalar quantity.

It is measured by beam balance.

Mass of the object remains constant at all the places.

We can measure mass of an object by its inertia.

SI unit of mass is ”kg”.

brainlest answer plz ..

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:
