In this picture B, D, and F are midpoints. Ac=50, CE=60, and BD=35

Icould really use some with this question.

What is the factored form of the following expressions? d^2 – 13d + 36

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
