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

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me

Idon't get undoing if its pass adding and subtracting so can someone ? x-2 over 5 = 18
