Answer:
Domain
Step-by-step explanation:
The <u>domain</u> tells you all of the possible x-values in a set of data.
The example uses ordered pairs written as (x, y), and takes out all of the x-values. It wrote the domain in set notation (which is when the { } curly-styled parentheses are used).
Do not confuse domain with range. Range means all of the y-values in a relation.
In the provided example, the range would be {3, 4, 5, 7}.
17) 3*5 + 4 = 19
18) 2 * 3 = 6
19) 3 * 36 + 2 * 6 + 1 = 121
20) 5 * 49 + 6 * 7 = 287
21) 6 * 64 + 6 * 8 + 6 = 438
22) 1 * 81 = 81
23) 1 * 8 + 1 * 4 = 12
24) 7 * 729 + 5 = 5108
25) 1 * 1296 + 5 * 216 + 2 * 36 = 2448
26) 1 * 16 + 1 * 2 = 18
27) 4 * 3125 + 1 * 25 + 2 * 5 + 3 = 12538
The square root of 24 would be plotted between 4 and 5, but closer to 5 on a number line.

What is a number line?</h3>
A number line is a horizontal line with evenly spaced numerical increments. The numbers on the line will dictate how you answer the number on the line.
A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, denoted by \mathbb {R}. Every point on a number line is assumed to be a real number, and every real number is assumed to be a point.
Number lines are extremely adaptable, that can be used to locate numbers, compare numbers, fractions and mixed numbers, decimals, integers, absolute value, addition, subtraction, inequalities, multiples, common denominators, and much more.

<h3>
Answer: The rectangles are <u>
not</u>
similar</h3>
========================================================
Explanation:
Divide the vertical sides to get the fraction 18/7
Divide the horizontal sides to get the fraction 30/6
If the rectangles were similar, then 18/7 = 30/6 is a possibility (there's one more possibility but we'll get to it later).
If 18/7 = 30/6 were true, then we should be able to cross multiply and get another true statement. Let's find out
18/7 = 30/6
18*6 = 7*30
108 = 210
We get a false statement, which means the original equation is false.
-----------------------
Now let's say we rotated the bottom rectangle so that the '7's were horizontal and the '6's were vertical. We'll divide the corresponding horizontal sides and vertical sides to get the two fractions of 30/7 and 18/6
Let's see if we have a true equation or not
30/7 = 18/6
30*6 = 7*18
180 = 126
Like before, we end up with a false equation which means the original is false.
No matter how we rotate the rectangles, we do <u>not</u> end up with similar figures.
-----------------------
Here's another way to see we don't have similar rectangles. We'll form the fraction 18/30 based on dividing the vertical and horizontal sides of the upper rectangle. The lower rectangle gives us 7/6
18/30 = 7/6
18*6 = 30*7
108 = 210
This is more evidence that the rectangles aren't similar. The same will happen if we tried 18/30 = 6/7
