Answer:
D. 10x - 5
General Formulas and Concepts:
Algebra I
- Terms/Coefficients/Degrees
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 5x
g(x) = 3x - 5
(f + g)(x) is f(x) + g(x)
Step 2: Simplify
f(x) = 7x
g(x) = 3x - 5
Step 3: Find
- Substitute: (f + g)(x) = 7x + (3x - 5)
- Combine like terms: (f + g)(x) = 10x - 5
