Question

Find 3A +2B A = [3 4 6 2] and B= [2-4 -1 5]

Answer 1

To find 3A +2B with given vectors A = [3 4 6 2] and B= [2 -4 -1 5], perform scalar multiplication on each vector and then add the results.

Step-by-step explanation:

To find 3A +2B with given vectors A = [3 4 6 2] and B= [2 -4 -1 5], we can perform scalar multiplication on each vector and then add the results.

First, 3A = 3 * [3 4 6 2] = [9 12 18 6].

Then, 2B = 2 * [2 -4 -1 5] = [4 -8 -2 10].

Finally, we add the two results: 3A + 2B = [9 12 18 6] + [4 -8 -2 10] = [13 4 16 16].

Answer 2

3A = [9 12 18 6]
2B = [4 -8 -2 10]

3A +2B = [13 4 16 16]
