<h3>
Answer: A and C</h3>
Both matrices are 1 x 4 matrices. This notation says there is 1 row and 4 columns. The number of rows must match up, as well as the number of columns, in order for matrix addition to be possible. This is so the corresponding elements pair up and add together. For instance, the 5 and -2 pair up and add together for matrices A and C.

Answer: 40%
Step-by-step explanation:
Let the percentage of 22 that gives 8.8 = x% ---------------------------1
Therefore,
x% of 22 = x/100 x 22 ------------------2
since this gives 8.8, we now equate to equation 2
x/100 x 22 = 8.8
(22 x X )/100 = 8.8
22x/100 = 8,8
Now cross multiply to solve for x
22x = 8.8 x 100
22x = 880
Now divide through by 22 to get the require value of x
x = 880/22
x = 40%
