The work above shows division of a polynomial by a binomial using long division. what is the remainder?

remainder = 16

Step-by-step explanation:

It seems as if the bulk of the division has already been done, the next step is to just subtract the two binomials to get the remainder as one would in normal long division with real numbers.

-x+12-(-x-4) (original expression)

-x+12+x+4 (distribute the negative)

16 (combine like terms)

The remainder of the division would be 16.

20

step-by-step explanation:

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.
