Answer:
20
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x
Substitute x = 2 into f(x) + g(x)
(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20
Took 3 of us in grade 10 but johns present age is 77.5 and his sister is 72.5
The previous question I answered was exactly like this.
6(4) - 2(6) = 12.
K = 4.
