What is the product of the following two matrices? In my book, the answer is A, while I believe it is B because if c1 = r2 , then a product exists. However, this is not upheld in this given question because c1 = 1, and r2= 4.
Here is the problem:
The product of (-2 -1 5 9) (0 -5)
(-7 1) is:
B) product is not defined
The other choices are irrelevant to my question.
Thank you for the help, it is greatly appreciated.
