<u>Matrix:</u> A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.
Horizontal lines are called rows and vertical lines are called columns.
<u>Order of Matrix:</u> A matrix containing x rows and y column has order x × y and it has xy elements.
<u>Different types of matrices:</u>
Row Matrix: This type of matrices have only 1 row. <u>Example:</u>
<u>Column Matrix:</u> This type of matrices have only 1 column. Example:
<u>Square Matrix:</u> In this type of matrix, number of rows and columns are equal. Example:
<u>Zero Matrix:</u> It is a matrix with all elements present is zero. Example:
<u>Identity Matrix:</u> In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:

Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Total point = 818
Let number of 3 point goals = p
Number of 2 point goals = 2p - 69
Number of 1 point = 2p - 69 - 28 = 2p- 97
3p + 2(2p - 69) + 1(2p - 97) = 818
3p + 4p - 138 + 2p - 97 = 818
9p - 235 = 818
9p = 818 + 235
9p = 1053
p = 117
Hence ;
number of 3 point goals = 117
Number of 2 point goals = 2(117) - 69 = 165
Number of 1 point = 2(117) - 97 = 137
I worked this out, and the answer is B.) 14x+6
