Question

Please help! Correct answer only, please! I need to finish this assignment this week. Find the product AB, if possible. Explain if it is not possible. A. B. C. D.

Answer 1

Answer:

A

Step-by-step explanation:

It is possible because the dimensions of A is 3x1 and B is 1x3, and you can only multiply if the colums of A is equal to the rows of B which in this case is.

Then to multiply, you start from 1 and multiply with 5 then 0 then 4 and then multiply 5 (from A) with 5 (from B) and so on.

1(5)     1(0)     1(4)                                        5         0         4

5(5)    5(0)    5(4)                     =               25        0        20      

-3(5)   -3(0)   -3(4)                                      -15        0       -12

Hope this helps!
