Answer:
x² + 2x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= 2x + 3 + x² - 8 ← collect like terms
= x² + 2x - 5
Answer:

Step-by-step explanation:
Given that,
Distance, d = 100 mile
Velocity of the winner, v = 120.1229 mph
We know that velocity of an object is equal to distance per unit time. Let t is the time. So,

Hence, 1.201 hour is taken by the winner.
