Divide 32x4 − 12x2 + 7x by 2x.
what is the quotient?
16x4 − 6x2 + 7
2 x
16x3 − 6x + 7
2
16x3 − 6x + 7
32x3 − 12x + 7

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

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.
