‏Good morning, what is the ‏meaning of this
‏The timer will not begin until after the set up process is finished.
‏I appeared and I have a
‏quiz !

Uhm, in my opinion. This means that when you do something and you wanted to record the time of how long you do it, you must first prepare, get the things you need, prepare yourself, memorize the steps. If you have done it then now start the timer.

never fear papaguy is here

answer

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.
