The perimeter of a square is 40x^4+16x^2. Find the area.

Step-by-step explanation:

4*side=40x^4+16x^2

side=10x^4+4x^2

area=(10x^4+4x^2)^2=(x^2)^2(10x^2+4)^2

=x^4(100x^4+80x^2+16)

=100x^8+80x^6+16x^4 sq. units.

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.
