Answer:
Calgary is the coldest
Step-by-step explanation:
The simple way to determine this will be to change the value of temperatures given in Fahrenheit to Celsius
32 F = 0°C
Formula to apply will be (T-32)×5/9 -------------where T is temperatures in Fahrenheit
Bangor is -3F-------------------change to Celsius
(-3-32)×5/9 =-35 × 5/9 = -19.44°C
Fairbanks is -12 ------------------------change to Celsius
(-12-32)×5/9 = -44 × 5/9 = -24.44°C
Fargo is -8 F ---------------------Change to Celsius
(-8-32)×5/9= -40×5/9 = -22.22°C
Calgary is -15 F-------------------------Change to Celsius
(-15-32)×5/9 = -47×5/9 = -26.11°C--------------coldest

Answer: 110 mph
Step-by-step explanation: 275 / 2.5 = 110 mph
2x^2 + 4x + 1 = 0
2x^2 + 4x + 1 - 1 = 0 - 1
2x^2 + 4x = -1
X(2x + 4) = -1
X = -1.
2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.
I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
