Given:
10 cousins
1 Jackson cousin
twice as many Lopez cousin as Chen cousin.

The unknown are the number of Lopez cousin and Chen cousin. 

Let x represent the number of Chen cousin. Since Lopez cousin is twice the number of Chen cousin, the Lopez cousin is represented by 2x.

1 + 2x + x = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3 → Number of Chen cousins

2x → 2(3) = 6 → Number of Lopez cousins

There is 1 Jackson cousin, 6 Lopez cousins, and 3 Chen cousins. For a total of 10 cousins.

What is the perimeter of the quadrilateral shown below?
GarryVolchara [31]

The perimeter of a shape is the sum of the lengths of its sides.

So, to find the perimeter of this quadrilateral, all we have to do is add the side lengths and simplify.

(x² - 6) + (2x + 5) + (x² - 3x) + (4x² + 2x)

x² + x² + 4x² + (-3x) + 2x + 2x + (-6) + 5

6x² + (-3x) + 2x + 2x + (-6) + 5

6x² + x + (-6) + 5

6x² + x + (-1)

6x² + x - 1

So, the perimeter of the quadrilateral is the quantity (6x² + x - 1).

Hope this helps!
