==================================================
Work Shown:
7(-2-7k) + 4
7(-2) + 7(-7k) + 4
-14 - 49k + 4
-49k + (-14+4)
-49k - 10
In the second step, I distributed the outer 7 to each term inside. From there, I grouped and combined like terms, which were the -14 and 4.
Answer:
1/4
Step-by-step explanation:
What is the question?
|4r−12| = -(4r-12) when 4r-12< 0
4r< 12 so r<3
13
subtract 1 on both sides
then divide by 3
to get 13
