Solve by factoring aka zero product property method. if the equation has no real solutions, write no real solutions. 3. x^2 − 5 + 4 = 0 4. x^2 + 7 + 12 = 0

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
