Question

Ramone wrote the following matrix equation.

A+(8 -12 3)=
(0 18 -21)




Which explains why Ramone’s equation has no solution?
There is no number that when summed with 8 equals 0.
The matrices must be of the same size in order to perform addition or subtraction.
The sum of 8 and –12 is not 3.
The matrices must measure 2 X 2 in order to be added together.

Answer 1

Answer:b

Explanation:

Answer 2

Assuming matrix A is 1 * 1 then the ramone equation has no solution because it would be the sum of a scalar with a matrix. Which would not make sense. The matrices must be of the same dimensions to be added.
answer
The matrices must be of the same size in order to perform addition or subtraction.
