Step-by-step explanation:
|-2x-10| + 4 = 2
Subtract 4 from each side
|-2x-10| + 4-4 = 2-4
|-2x-10| = -2
The absolute value is negative so there are no solutions.
Absolute values are always positive, so they cannot be negative.
To know the life span of the wolf and the lion, we simply substitute their mass to the formula for L.
Mass of wolf:
Mass of lion:
