For all values of x, f(x) = x/5 + 3
and
g(x) = 10x²+ 5
Work out fg(x).
Give your answer in the form ax2 + b where a and b are integers.

fg(x)=f(10x²+5)=(10x²+5)/5+3=10x²/5+5/5+5

=2x²+1+5=2x²+6

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:
