Factor 140c + 28 - 14a to identify the equivalent expressions.
Feliz [49]

Answer:

The answer to your question are letters A, C and D.

Step-by-step explanation:

To factor this polynomial we need to look for the common factor of the three terms.

To find it, get the greatest common factor

                        140    28   14     2

                          70    14     7     2

                          35     7     7     5

                            7     7      7     7

                             1     1       1    

Greatest common factor = 2 x 7 = 14  

Factor the polynomial

140c + 28 - 14a = 14 ( 10c + 2 - a)

Factor only 7          7(20c + 4 - 2a)

Factor only 2          2 (70c + 14 - 7a)
