Fractional form: 63/10 or 6 3/10.
The length of the missing side of the triangle is 6 cm.
<h3>
Triangle</h3>
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, obtuse and scalene triangle.
The perimeter of a triangle is the sum of all the sides of the triangle. Let x represent the missing length. Also, let the other sides be 3 cm and 10 m.
Hence:
Perimeter = x + 3 + 10
19 = x + 13
x = 6 cm
The length of the missing side of the triangle is 6 cm.

Answer: 603
<u>Step-by-step explanation:</u>
Average rate of change is the slope over the given interval.
Interval [7, 9] is between x = 7 and x = 9. Use the table to see that the coordinates are (7, 1852) and (9, 3878). Then use the slope formula:
Interval [4, 6] is between x = 4 and x = 6. Use the table to see that the coordinates are (4, 358) and (6, 1178). Then use the slope formula:
Next, find the difference between the slopes above:
[7, 9] - [4, 6]
= 1013 - 410
= 603
It will be a relation because at every place on that graph when you draw a vertical line, it will go through the graph at more than one place (except for at each vertex, but that doesn't matter).
