Answer:
clockwise from left, the missing side lengths are 8 m, 13 m, 8 m
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...
38 = (3x+1) +(2x) +(9) +(2x)
38 = 7x +10
28 = 7x . . . . . . subtract 10
4 = x . . . . . . . . divide by 7
Then the short sides are ...
2x = 2·4 = 8 . . . meters
and the long side is ...
3x+1 = 3·4 +1 = 13 . . . meters

Answer:
B
Step-by-step explanation:
2x + 4y = 6x - y
4y + y = 6x - 2x
5y = 4x
(4,5) when x=4, y=5
5(5) = 4(4)
25 = 16
is a false statement, so not (4,5)
(5,4) when x=5, y=4
5(4) = 4(5)
20 = 20
is a true statement, so yes
