Final answer:
The equation has no solution when x>0.
Step-by-step explanation:
To solve the equation x³+5=-4x when x>0, we'll simply substitute the given value of x into the equation.
Plugging x=1 into the equation, we get:
(1)³+5=-4(1)
1+5=-4
6=-4
This is not a true statement, so x=1 is not a solution to the equation. Therefore, there is no possible solution when x>0.
