we have the coordinates of ABCD
there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way
distance between 2 point =
AB
AB = 4.24
now repeat the same with all
BC= 4.24
CD= 4.24
DA= 4.24
so its a square with all the same sides so perimeter is 4 x 4.24
perimeter is 16.96
hope this helps
mark me as brainliest please

Answer:
(x, y) = (2, -6)
Step-by-step explanation:
Subtract the first equation from the second.
(8x -2y) -(5x -2y) = (28) -(22)
3x = 6
x = 2
Substitute this into either equation and solve for y.
8(2) -2y = 28
8 -y = 14 . . . . . . . . divide by 2
y = 8 -14 = -6 . . . . add y-14 to both sides
The solution is (x, y) = (2, -6).

I like a graphing calculator for a quick solution to such problems.
Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are
The sum of these x -coordinates is
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus, and we solve for x
Using Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are:
The sum of these x -coordinates is
We can check our work with the graph of the two polynomials.
