N-8 or 8-n I would assume
One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?
2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)
To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.
