175 red squares out of 1000 squares = 175/1000 = 0.175 of the design is red.
Answer:
4 8 12 16
3 6 9 12
Step-by-step explanation:
Given:

First, let us find two points from this equation.
We can set values of x and then solve for y.
Let us find the values of y when x = 1, 2, 3, 4, 5

We now have a set of points:
(1, 21)
(2, 16)
(3, 11)
(4, 6)
(5, 1)
Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)
The graph would then look like this:
So perimeter is equal to 2 lengths and 2 width so the equation would be P=2L+2W. you know width so you plug in 5 for W then solve for L and you should get L=3
It should be 16, but because there is only 2 examples, I'm not totally sure. But, I hope this helps you! :)
