MN = √2
it comes from √(1^2 + 1^2) = √2 (use phytagoras)

LK = 2 x MN = 2 √2

NK = √(2^2 + 1^2) = √5

ML = NK = √5

so the perimeter
√2 + 2 √2 + √5 + √5
3 √2 + 2 √5

Solve the system of equations.in this form: (x, y)<br><br> -5y + 8x = -18<br><br> 5y + 2x = 58

Gre4nikov [31]

If we add the equations it looks like
-5y + 8x + 5y + 2x = -18+58
so 10x=40
so x=40/10=4
now let's replace x by 4 in the second equation
5y +2*4=58
5y=58-2*4=58-8=50
so y=50/5=10
so (x, y) = (2, 10)
