Answer:
The last image (The one going through points (4,1) and (8,2))
Step-by-step explanation:
If the side length is y, and the perimeter is x, x is equal to that value times 4. This means the table of points would look like this:
x y
4 1
8 2
12 3
And so on. The only graph that is going through these points is the last one. The third graph is wrong because it's the opposite, (1,4) instead of (4,1), and the perimeter will be greater than the side length.
So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so
([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])
or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5
number 2
since 11 is 1/2 of 22 it can be written as
the square root of 3 or 3^(1/2)
