Answer:
The area of the rectangle A = 25x² - 20x
Step-by-step explanation:
Given
The width of the rectangle = w = 5x - 4
The length of a rectangle = l = 5x
To determine
The area of the rectangle = ?
Using the Formula to determine the area of the rectangle
substitute w = 5x - 4 and l = 5x in the formula
Apply distributive law: a(b-c) = ab - ac
as 5x(5x) = 25x² and 4(5x) = 20x, so
Therefore, the area of the rectangle A = 25x² - 20x
For each of the following distance matrices of graph, the
- The diameter = 3
- The radius of the graph is given as 2
This is used to refer to the fact that there would be a maximum distance that exists between the pair of vertices.
<h3>What is the radius of the graph</h3>This used to refer to the minimum eccentricities of the vertices
<h3>What is the center of the graph?</h3>This is used to show all of the vertices that have minimum eccentricities.
<h3>How to solve the matrix</h3>We have
e 1 = 3
e 2 = 3
e3 = 2
e4 = 3
e 5 = 3
e 6 = 3
e 7 = 3
e8 = 2
e 9 = 3
e 10 = 2
Then the the diameter = maximum eccentricity = 3
The radius = minimum eccentricity = 2
center = [3, 8,10]
