Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours

Answer:
f(4) = 2
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 6
g(x) = x²
Step 2: Find g(-2)
g(-2) = (-2)²
g(-2) = 4
Step 3: Find f(g(-2))
f(g(-2)) = f(4)
f(4) = 2(4) - 6
f(4) = 8 - 6
f(4) = 2
