6) Suppose Preston comes back to the tree years later and places the mirror the exact same distance from the tree. If the tree has grown to 25.38 feet tall and Preston has grown 3 inches (0.25 feet), how far must he stand from the mirror now in order to exactly see the top of the tree?

Can somebody me out with this question

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
