K (-3,-3)
L (1,-1)
M (-1,-5)
N (-5,-7)
Answer:

Step-by-step explanation:
We can factor out a 1 from -3 to get
.
We know from simple arithmetic that
.
So, our answer is 
So the length is 4*28=112mm
The width would be calculated like this:
you draw an equilateral triangle in the middle with sides or 2r(56mm). The based on pythagorean theorem u know that
h=rad(56^2-28^2)=48.497
28+28+h=104.497
The area would be S=l*w which is 11703.7113mm
Answer:No solution
Explanation: There is no solution because x was eliminated in the last step of solving for x. Since we were left with x not being available to equal three, it shows it’s a no solution problem. Hope this helped!
Answer:
A one solution I hope that help
