In order for a relation (a set of ordered pairs) to be considered a function, every value in the domain (the set of all the first numbers in the pair) is associated with one value in the range (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if every value in the domain only has one arrow coming out of it. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.

The area of a rectangle is 300 square centimeters. If the sides of the rectangle are given as 5 centimeters and <img src="https:

x is 1000, and the other side of the rectangle is 60 cm.
Area is found by multiplying length by width. Using the sides we know we have
$300=5(\sqrt{x+2600})$
We divide both sides by 5:
$\frac{300}{5}=\frac{5\sqrt{x+2600}}{5}
\\
\\60=\sqrt{x+2600}$
To "undo" a square root, we square both sides:
$60^2=(\sqrt{x+2600})^2
\\
\\3600=x+2600$
Subtract 2600 from both sides:
3600-2600=x+2600-2600
1000=x
Now we substitute this into the side with x:
$\sqrt{x+2600}=\sqrt{1000+2600}=\sqrt{3600}=60$
