Answer:
15
Explanation:
is a matrix exercise, here we must match each number with each letter (respectively), i.e. 1x1(of A) with 1x1(of B).
"F" is in the second row and third column, as is 6; "I" is in the third row and third column, as is 9; we just match and there is nothing more to do.
F= 6
I= 9
F+I = 9+6 = 15
