Mr. Smith used 17 lengths of fence to enclose his gardens. He now needs 6 lengths of fence for a dog kennel. Show how he can remove 6 lengths of fence and still have 2 squares. Please help!Thanks!

Let E be the electric bill and G be the gas bill E = 3 + 1/2G 92 = 3 +1/2G 92-3=1/2G (89=1/2G) x 2 89x2=G 178=G So, the gas bill was $178.00
