What is the value of the entry represented by c41
Elenna [48]

<u>ANSWER</u>

C_{41}=2

<u>EXPLANATION</u>

This very simple to do.

First locate the entry in A_{41} in matrix A. That is the entry in the intersection of the fourth row and first column of matrix A. This entry is  7.

Then multiply by the scalar which is 2 to get,

2\times 7=14.

Next we locate the entry in B_{41} in matrix B also. Which is 4. We multiply by the scalar of -3 to get,

-3\times 4=-12.


We now add these two corresponding entries to obtain,

14+-12=14-12=2

Answer:I believe your answer should be C: 23/15

Step-by-step explanation:

So you add 11/15 and 12/15 since the common denominator is already 15 you only need to add the numerator which is 11 and 12 and 11+12= 23 thus you get 23/15
