URGENT :)) PLS HELP!

(Q4)
Given Matrix A consisting of 3 rows and 2 columns. Row 1 shows 3 and negative 1, row 2 shows 2 and 0, and row 3 shows negative 3 and 3. and Matrix B consisting of 3 rows and 2 columns. Row 1 shows 3 and 3, row 2 shows negative 5 and 4, and row 3 shows negative 4 and 2.,

what is A − B?

a) Matrix consisting of 3 rows and 2 columns. Row 1 shows 0 and negative 4, row 2 shows negative 3 and negative 4, and row 3 shows 1 and 1.
b) Matrix consisting of 3 rows and 2 columns. Row 1 shows 0 and negative 4, row 2 shows 7 and negative 4, and row 3 shows 1 and 1.
c) Matrix consisting of 3 rows and 2 columns. Row 1 shows 0 and negative 4, row 2 shows 7 and 4, and row 3 shows negative 1 and 0.
d) Matrix consisting of 3 rows and 2 columns. Row 1 shows 6 and 2, row 2 shows 7 and 4, and row 3 shows negative 7 and 1.

Answer 1

The difference between two matrices of the same size is calculated by subtracting the corresponding elements of the two matrices.

Let’s apply this to matrices A and B:

A - B = [3 -1; 2 0; -3 3] - [3 3; -5 4; -4 2] = [0 -4; 7 -4; 1 1]

So the correct answer is B) Matrix consisting of 3 rows and 2 columns. Row 1 shows 0 and negative 4, row 2 shows 7 and negative 4, and row 3 shows 1 and 1.
