Answer:
All of the above.
Step-by-step explanation:
The way to calculate velocity is d/t, the displacement over time of travel. Hence, both of those are needed.
Finally, velocity also needs to know your direction, like 5 m/s East for example. Hence, all of the above are needed.
Hope this helped!
I think its the... second.... please correct me if im wrong :(
Answer:
units
Step-by-step explanation:
The perimeter of a square is 4 times the length of one side.
The length of the sides of a square is given by the expression 
To find the perimeter, we multiply this expression by 4.

We expand to obtain:

This simplifies to:

Answer:
Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.
<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>


<em>Now solve what remains in the parentheses.</em>


<em>Finally, subtract 4 from 10 and get your answer:</em>
