- 18
2- 20
= -18
Because you do the same thing just going to end up with a negative.
Average speed=(total distance traveled)/(total time of travel)
average speed=(120+48)/3

<h2>
Answer:36 
</h2>
Step-by-step explanation:
Given that
is isosceles triangle.
A isosceles has two sides equal an the third side is the base.
So,
...(i)
Given that length of the base 
Given that the perimeter of the triangle is 
So,
...(ii)
Using (i) and (ii),

Answer:
asymptotically stable.
Step-by-step explanation:
Equilibrium solutions in which solutions that starts near and then moves away from equilibrium solutions are asymptotically unstable. Equilibrium solutions which solutions starts nears and then move towards the equilibrium are asymptotically stable.
