I don’t really get what you’re asking here but a system of 2 parallel lines has no solution, and a system of 2 parallel lines is called inconsistent.
(6k+2)-(3k-2)
expand brackets 18k²-12k+6k-4
simplify 18k²-6k-4
9(2) + 2(y) = 50. solve for y. 32=2y, y=16. It is 16 meters long.
This is what I got
Area= 31.83 rounded would be 32
Radius= 3.18 rounded would be 3
Diameter= 6.37 rounded would be 6
