To subtract the expression \((s + 9)\) from \((5s + 9)\), you can distribute the negative sign across the second expression: \[ (5s + 9) - (s + 9) = 5s + 9 - s - 9 \] Now, combine like terms: 1. Combine the \(s\) terms: \(5s - s = 4s\) 2. Combine the constant terms: \(9 - 9 = 0\) Putting it all together: \[ 4s + 0 = 4s \] So, the result of the subtraction is: \[ \boxed{4s} \]
