Answer:
s=8
Step-by-step explanation:
Let's solve your equation step-by-step.
s(11−s)=24
Step 1: Simplify both sides of the equation.
−s2+11s=24
Step 2: Subtract 24 from both sides.
−s2+11s−24=24−24
−s2+11s−24=0
Step 3: Factor left side of equation.
(−s+3)(s−8)=0
Step 4: Set factors equal to 0.
−s+3=0 or s−8=0
s=8
