Which of the following matrices products are defined?

Answer:

EB is defined

BE is defined

BD is defined

and DA is defined

Step-by-step explanation:

To know that the product of two matrices are defined, the column of the first matrix must be the same as the row of the second matrix.

For example; for EB we have 5 columns for E and 5 rows for B. After this product is done it produces a matrix with dimension 3 x 3, which means 3 by 3 (3 rows by 3 columns)

Check the picture below.

the one on the left is a regular octagon, as well as a convex one.

the one on the right is also an octagon, but is concave, the  issue is that, though all sides remain equal, the angles do not, and so is not a regular octagon.

What is the quotient of 28 divided by 7 increased by 4

Answers

The quotient after increased by 4 is 8.

To calculate the quotient of 28 divided by 7, we perform the division and get:

28 ÷ 7

= 28/7

= (7 x 4)/ 7

= 4

Next, we are asked to increase this quotient by 4. Adding 4 to the quotient:

= 4 + 4

= 8.

Therefore, the quotient after increased by 4 is 8.
