Jay will use wood planks to make a rectangular border for his garden. The garden has an area of 63 square feet and a width of 7 feet. Jay already has a 12 foot wood plank that can be cut into smaller pieces. How many more feet of wood planks must he buy?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
