Shauna solved the polynomial equations given in the table. Determine whether each polynomial is correct. Select Correct or Incorrect for each equation. Equation Correct Incorrect (5a−8)+(2a2+2a−1)=2a2+7a−9 (b2+6b−4)−(3b+b2)=2b2+3b−4 (9c−4c2)−(2c2+c)=−6c2+10c

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
