Factor completely −4x2 + 16x − 24.

a. −1(x2 − 16x + 24)
b. −4(x2 − 4x + 6)
c. −4x(x2 − 4x + 6)
d. −4(x2 + 4x − 6)

Option B is correct

factor completely of is

Step-by-step explanation:

GCF(Greatest Common Factor) states that the largest factor that divides the polynomial.

Given the expression:

By definition of GCF we have;

Factor a GCF of the given expression.

Since GCF of , and -24  is -4

then;

Therefore, factor completely of is

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

hope this ! mark brainliest!

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.
