meriva

Answer:

\large\boxed{x=-\dfrac{1}{5}}

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)

In order from greatest to least, the ribbons go

7/8 (Green)
3/4 (Pink)
1/3 (Blue)

This because 7 out of 8 is a larger number than 3 out of 4, and 3 out of 4 is greater than 1 out of 3.
