Is it 22.5 b/c 22.5 *2 = 45 and 22.5 +22.5= 45. or do u mean both numbers have to be the same
9 - 2c + c = -13
9 - 3c = -13
-3c = -22
c = 7 1/3
The wind chill equations I have found are more complicated than that.
Answer:
3, -8 , 11.
Step-by-step explanation:
f(x) = (x - 3)(x + 8)(x - 11)
Finding the zeros:
(x - 3)(x + 8)(x - 11) = 0
x - 3 = 0 gives x = 3.
x + 8 = 0 gives x = -8.
x - 11 = 0 gives x = 11.
