Mark and Nina own different flower shops, which both open at the same time in the morning. Function m models the number of roses Mark has at his flower shop, and function n models the number of roses in Nina's flower shop, x hours after the shops open. m(x) = 616 - 24x (x) = 552 - 36x Which function correctly represents how many more roses Mark has at his flower shop than Nina has at hers, x hours after the shops open? А. (m-n)(x) = 64 + 12x

B. (m-n)(x) = 64 - 12x

C. (m-n)(x) = 64 - 60x

D. (m-n)(x) = 64 - 16x​

answer: idk

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.
