5. solve (2x - 1)2 = 8 using the quadratic formula.

x= 4/10 or simplified to  2/5

Step-by-step explanation:

multiply 2 by both (2x-1)= 4x-2=8

add 2 to both sides 4x=10

divide 4 from both  sides x=4/10

simplify= 2/5

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.
