AB formed by (-6, 2) and (-2, 4) CD formed by (-1, 11) and (5, -7)

a

step-by-step explanation:

a

the answer for this question is 38

i can't see the picture : /

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
