SOLUTION: C(A+B) A =0 4 -3 B=1 1 0 1 4 6 -6 6 1 C= 6 1 6 4 -3 4 Use the following matrices to compute C(A+B). THANKYOU!

Question 1106453: C(A+B)
A =0 4 -3 B=1 1 0
1 4 6 -6 6 1
C= 6 1
6 4
-3 4
Use the following matrices to compute C(A+B). THANKYOU!
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
A is a 2 rows by 3 columns matrix
B is a 2 rows by 3 columns matrix
:
therefore (A+B) is a 2 rows by three columns matrix
:
C is a 3 rows by 2 columns matrix
:
therefore, C(A+B) is defined and it is a 2 by 2 matrix
:
(A+B) is
1 5 -3
-5 10 7
:
Note that we add corresponding elements of both matrices
:
C(A+B) is
:
6+30+9 1+20-12
-30+60-21 -5+40+28
:
45 9
9 63
:
Note that we multiply the elements of each row by the elements of each column
