Respuesta :

Answer D.

Explanation:

7(1-k) to solve that you have to multiply 7 for 1 and for -k

You get 7 - 7k

If you have to factorize 7-7k you do the GCD between 7 and 7k (it's 7!) and then divide 7 and -7k by 7

You get 7(1-k)

Hope it was clear

The answer is d because 7 times 1 =7 and 7 times -k is -7k

d.7(1-k) and 7-7k
