Answer:
x =1, x = 0 is extraneous.
Step-by-step explanation:
5/x = 4x + 1 / x^2
5x^2 = 4x^2 + x
5x^2 - 4x^2 - x = 0
x^2 - x = 0
x(x - 1) = 0
x = 0, 1.
x is not a solution because 5/x is undefined.

Answer:
At 6 pm, the temperature was 13°C below the freezing point
Step-by-step explanation:
Let us first express the information clearly to determine the temperature at 6 p.m:
The temperature in the morning = 6°C
the temperature at noon (12pm) = -13°C
It stayed at that temperature for six hours; this means that the temperature from 12 noon to 6 pm = -13°C
∴ Temperature at 6 pm = -13°C
Next let us calculate how far -13 is, below freezing point (0)
Difference = 0 - (-13)
= 0 + 13 = 13°C
Therefore, at 6 pm, the temperature was 13°C below the freezing point
