The quotient of 12 divided by the difference of 3 times d minus 3

0 = 0 infinity

Step-by-step explanation:

3 x d - 3 / 12 = 0

/d                     /d

3 - 3 / 12 = 0/d = 0

3 - 3 = 0

0/12 = 0

0 = 0

b, 20 yards

step-by-step explanation:

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.
