A cold drink initially at F warms to F in 4 min while sitting in a room temperature F. How warm will the drink be in degrees Farenheit if left out for 30 min

Which expression is equivalent to 2x^2+7x+4?

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

Are the corresponding angles congruent? explain why or why not.
