Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix

Answer: x < 9</h3>
Work Shown:
4x - 6 < 30
4x - 6 + 6 < 30 + 6
4x < 36
4x/4 < 36/4
x < 9
Explanation:
The idea is to undo everything happening to x. We follow PEMDAS in reverse. We undo subtraction first by adding 6 to both sides (step 2), then we undo multiplication by dividing both sides by 4 (step 4).
