Question

Dadas as matrizes A =
Me ajudem!!!

Answer 1

A = [0 3]

[2 -5]

B = [-2 4]

[0 - 1]

C = [4 2]

[-6 0]

a) A + B

[0 3]. [-2. 4]

+

[2 - 5]. [0. - 1]

0 + (-2) = 0 - 2 = - 2

2 + 0 = 2

3 + 4 = 7

(-5) + (-1) = - 6

[-2 7]

[2. -6]

b) A + C

[0 3]. [4. 2]

+

[2 - 5]. [-6. 0]

0 + 4 = 4

3 + 2 = 5

2 + (-6) = - 4

- 5 + 0 = - 5

[4. 5]

[-4. -5]

c) A + B + C

[0. 3]. [-2. 4]. [4. 2]

+ +

[2. -5]. [0. -1]. [-6. 0]

0 + (-2) + 4 = 2

3 + 4 + 2 = 9

2 + 0 + (-6) = - 4

- 5 + (-1) + 0 = - 6

[2. 9]

[-4. -6]
