For this case we must factor the following polynomial:

We can take common factor x:

To factor the expression within the parenthesis, we must find two numbers that when multiplied give 49 and when added together, 14 are obtained. These are: 7 and 7.

Thus, the expression is factored as:

Answer:

For 2/5 meter, it takes = 1 min.
For 1 meter, it is = 5/2 min.
Now, for 6 meters, it would be: 5/2 * 6 = 30/2 = 15
In short, Your Answer would be 15 minutes
Hope this helps!
You add all of the numbers up then divide them by the number of values you added
From the information we have, we can conclude that this quadrilateral is a rectangle. The reason behind this is because rectangles have two sets of parallel sides, which makes them different from squares.
