Add all the sides then divide by how many sides it is
The solution(s) of a system of linear equations give points of intersection of specific lines or planes.
The solution(s) of a system of linear inequalities give areas of intersection wherein any specific pair of points or lines are solutions.
PROCESS-WISE there are little differences between solving systems. However, multiplication and division by negatives reverses the signs in inequalities.
composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle. The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure

Step-by-step explanation:
When you say a random sample, this means that every member of the population will have a chance to be part of the sample.
