A) simplify the expression and explain each step.4(3x+2)-2b) factor the expression completely.20b-16 i didn't get any sleep and have to finish this quiz.

see below   PLEASE GIVE BRAINLIEST

Step-by-step explanation:

A)     4(3X + 2) - 2     =     12X + 8 - 2     =    12X + 6

B)     20b - 16     =  4(5b - 4)

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

that would be a prism, if not right, feel free to correct me
