QUESTION 3

1. Evaluate

Answer:

We notice the rules for Matrix addition: The matrices are assumed to all have the same dimensions

The first matrix has two rows and three columns (2x3). The second matrix have three rows and two

columns (3x2) and we can say the two matrices are haven’t the same dimensions. That mean the

sum of the two matrices are not possible

Final answ er

NOT POSSIBLE

QUESTION 4

1. If B =

find -3B.

Answer:

The term scalar multiplication refers to the product of a real number and a matrix. In scalar

multiplication, each entry in the matrix is multiplied by the given scalar

So that -3B=

QUESTION 5

1. Evaluate

Answer:

We notice the rules for Matrix addition: The matrices are assumed to all have the same dimensions

The first matrix has one rows and three columns (1x3). The second matrix have three rows and one

columns (3x1) and we can say the two matrices are haven’t the same dimensions. That mean the

sum of the two matrices are not possible

Final answ er

NOT POSSIBLE

QUESTION 6

1. Matrix A has dimensions 5 x 4. Matrix B has dimensions 4 x 3. These two matrices can be

multiplied.

Answer:

In order for matrix multiplication to be defined, the number of columns in the first matrix must be

equal to the number of rows in the second matrix

The number of columns in the first matrix equal 4, the number of rows in the second matrix equal

4 so that these two matrices can be multiplied

Final answ er

TRUE

FALSE

QUESTION 7

1. Matrix A has dimensions 3 x 2. Matrix B has dimensions 3 x 2. A x B will have dimensions

3 x 2.

Answer:

In order for matrix multiplication to be defined, the number of columns in the first matrix must be

equal to the number of rows in the second matrix

The number of columns in the first matrix equal 2, the number of rows in the second matrix equal

3 so that these two matrices can be multiplied. That mean A x B will have dimensions 3 x 2 is False

Final answ er

TRUE

FALSE

QUESTION 8

1. Evaluate

Answer:

To multiply two matrices. We multiply and add the elements as follows. We work across the 1st

row of the first matrix, multiplying down the 1st column of the second matrix, element by element.

We add the resulting products. Our answer goes in position a11 (top left) of the answer matrix

QUESTION 9

1. Evaluate

Answer:

In order for matrix multiplication to be defined, the number of columns in the first matrix must be

equal to the number of rows in the second matrix

The number of columns in the first matrix equal 2, the number of rows in the second matrix equal

3 so that these two matrices can be multiplied
