<u>Step 1: Define</u>
f(x) = 1 - x
g(x) = x² + 2x - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Solve</u>
- Substitute in functions: (f + g)(x) = (1 - x) + (x² + 2x - 5)
- Combine like terms (x): (f + g)(x) = x² + x - 5 + 1
- Combine like terms: (f + g)(x) = x² + x - 4

Answer:
Step-by-step explanation:
1)
Quantity of glass recycled each minute = 1/3 tons
We know that;
1 hour = 60 minutes
Hence,
Quantity of glass recycled in one hour = 1/3*60=20 tons
1 day = 24 hours
Quantity of glass recycled in 24 hours = 24*20 = <u>480 tons</u>
