Consider the Matrix shown below:

What is the value of LaTeX: B_{2,4}-B_{3,2}B 2 , 4 − B 3 , 2

Group of answer choices

-2

3

7

9

The value of   -  is 3 ⇒ 2nd

Step-by-step explanation:

The dimensions of any matrix are (m × n), where

Ex: Matrix A of dimensions (2 × 3) has 2 rows and 3 columns, where

means the element in the 1st row and 1st column

means the element in the 1st row and 2nd column

means the element in the 1st row and 3rd column

means the element in the 2nd row and 1st column

means the element in the 2nd row and 2nd column

means the element in the 2nd row and 3rd column

Now lets solve the problem

∵ The matrix B has 3 rows

∴ m = 3

∵ The matrix B has 4 columns

∴ n = 4

∴ The dimensions of matrix B are (3 × 4)

∵ means the element in the 2nd row and 4th column

∴   = 9

∵ means the element in the 3rd row and 2nd column

∴   = 6

- Find the value of -

∵ - = 9 - 6

∴ - = 3
