Answer:
The dimensions ⇒ 3 × 4
Step-by-step explanation:
* Any matrix has two dimensions
- Raw and column
- The dimensions very important in the operations on matrices
- We called the number of raw m and the number of column n
- We must write the number of raw before the number of column
- m × n is the dimensions of the matrix
* Example : If the dimension of a matrix is 2 × 3, that
means the matrix has 2 raw and 3 column
* Now lets look to our problem
∵ It has 3 raw and 4 column
∴ Its dimensions is 3 × 4
The common difference is 11, you can see this because the number goes up by eleven each time.
