What are all the expressions equivalent to 3x + 2(x − 1) − 4?

5x−6

Step-by-step explanation:

Let's simplify step-by-step.

3x+2(x−1)−4

Distribute:

=3x+(2)(x)+(2)(−1)+−4

=3x+2x+−2+−4

Combine Like Terms:

=3x+2x+−2+−4

=(3x+2x)+(−2+−4)

=5x+−6

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
