What is the coefficient of y in the expression 2 ⋅ 3 + 9y? Which expression represents "7 times the sum of 4 and y?"

Four expressions are shown:

10x + 6

12x + 4

2(5x + 3)

2(6x + 2)

step-by-step explanation:

i think it’s a i believe

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.
