Let b = [-1 3 6 -3]. find -4b. a. [-4 12 24 -12] b. [4 3 6 -3] c. [-3 1 4 -5] d. [4 -12 -24 12]

d. [4 -12 -24 12]

Step-by-step explanation:

This question is on multiplication in matrix

Given matrix B, -4B means -4 × matrix B

     B= [ -1 3 6 -3]

-4B = -4 [-1 3 6 -3]

-4B = [4 -12 -24 12]

ratio is 2 : 9

the answer is three

13.5 : 3
