A perimeter of a rectangle is:

They give you the width, but let's convert it to an improper fraction first:

The length is twice the width so it is:

Now, we are ready to solve, plug in values in the perimeter formula:

So, 40 is your answer.
16/8k - 24/8 + 2/5 + 10/5k
2k - 3 + 2/5 + 2k
4k - 13/5
Hope it helps :)
Answer:
52 / 27
Step-by-step explanation:
Answer:
(6x + 5)(7x² - 6)
Step-by-step explanation:
Factor the first/second and third/fourth term
42x³ + 35x² - 36x - 30
= 7x²(6x + 5) - 6(6x + 5) ← factor out (6x + 5) from each term
= (6x + 5)(7x² - 6)
