can anyone help me in pre algebra? im in 8th grade, i need to get to a 70% which is a c- by january 24th. right now i have a 66.02% which is a d. its all basically modules, and functions. it would mean the world, you have to have social media: (snap, dc, insta, ect).

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
