Find the greatest common factor of:
25&15

5

Step-by-step explanation:

5x5 5x3 idk how to explain

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

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
