State the restriction on the following simplified expression:
7/x(x+5)
(Show steps)
The restriction on the expression 7/x(x+5) is that x cannot be equal to 0 or -5 because division by zero is undefined.
Steps:
1. Set the denominator equal to zero and solve for x:
x(x+5) = 0
x = 0 or x = -5
2. Therefore, x cannot be equal to 0 or -5.
