Answer:
s(r(2)) = 6
Step-by-step explanation:
You would first solve for r(2). You then input r(2) which equals -2 into s(r(2)).
r(x)= -2x + 2
r(2)= -2(2) + 2
r(2)= -4 +2
r(2)= -2
s(x)=x² + 2
s(r(2)) = (-2)² +2
s(r(2)) = 6

Answer:
455 miles
Step-by-step explanation:
Distance = Speed x Time
X = 65 x 7
X= 455 miles
If you are going 65 miles PER hour, then to find the total distance traveled, you'd mutiply the amount of time you have with how fast you are going.
10x6=60 so 180-60=120 and 120 divided by 8 is 15 so the answer is 15 hours
