using 3.14 for pi
area = pi x r^2
since he can see 12 miles in any direction 12 would be the radius
so 3.14 x 12^2 = 452.16 square miles
round the answer as needed.
Yes u need to explains or just take a picture
Answer:
5
Step-by-step explanation:
If <em>e = 7,</em> you would replace e in the expression <em>e - 2 </em>with 7 so that the expression becomes <em>7 - 2</em> which results in 5.
Does that help?
Answer:
8x miles
Step-by-step explanation:
- runs with speed 8 mph
- bikes at an average speed of 14 mph
distance = speed * time
Here the speed for run is 8 mph and time is x hours
So distance covered: 8 * x = 8x miles.
Answer:
Step-by-step explanation:
e) 3√2 (-3√6 -2 -6)
3√2 (-3√6 - 8)
-9√12 - 24√2
-9√(2^2 * 3) - 24√2
-18√3 - 24√2
or
6(-3√3 - 4√2)
f) -5√2 (3 + 2√2 - 6 - 1)
-5√2(-4 + 2√2)
20√2 - 20
or
20(√2 - 1)
