Answer: The value of
is
.
Step-by-step explanation:
Given: 
To find: 
As we know it is composition function which means that g(x) function is in f(x) function.
So we have
![(f_\circ g) (x) = f[g(x)]](https://tex.z-dn.net/?f=%28f_%5Ccirc%20g%29%20%28x%29%20%3D%20%20f%5Bg%28x%29%5D)

Now substitute the value of g(x) we get

Hence, the value of
is
.
First convert 1.2mm to cm
10mm = 1cm
so 1.2mm = 0.12cm
Then divide 1.44cm by 0.12cm
that equals to 12.
so you need 12 sheets to make it 1.44cm
