Use the properties of addition to find 37 + 58 mentally. Show your steps and identify the properties you used

47 - 90 = 43

43 - 180 = x

x = 137

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

the answer to your question is b.

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.
