Line m is represented by the following equation x-y=8 which equation completes the system that satisfied by the solution (18,10)? A 2x-y=26 b x+y=18 c 2x-2y=36 d x-y=-28

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

Are you trying to figure out the volume?
