Select the correct answer from each drop-down menu. the sides of sabc are 30 units, 40 units, and 60 units long. the corresponding sides of axyz are r times as long as the sides of abc. if the area of aabc is n square units, the area of axyz is the expression that gives the perimeter of axyz is square units.

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
