Referring the truth table in problem 6, list the wffs that are equivalent to a b. 8) referring the truth table in problem 6, list the wffs that are equivalent to the negation of a 8. 9) assign truth values to a, b, and c to prove that (a a b) v c is not equivalent to a a (b v c). c: b: a: (circle one of true or false) (aa b) v c is true or false (a a b) is true or false aa (bv c) is true or false (bv c) is true or false

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.

3x-x+2=4 i think that's is the answer, and i hope it you
