Answer:
The correct answer is A.
Step-by-step explanation:
The area of a rectangle can be calculated using the following formula:

If we know that the area measures
and one side of the figure measures 4.2 m, we can say that:

We isolate the side we don't know:

So I = 9 m
To know the perimter of a rectangle, we use the following formula:



Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation.
First of all, a relation is just a set of ordered pairs like you see in this problem. The domain is the set of all x-coordinates for those ordered pairs. So in this case the domain or D is {2, 5, -1, 0, -3}.
The range is the set of all y-coordinates for those ordered pairs. So in this case our range or R is {4, 3, -4, 9, 1}.
Answer:
If a graph is an Euler Circuit that mean that it can be traversed and begins and has all even verticies. This allows you to start and stop at the same verticie.
