Direction: Draw a box() if it is an expression and a triangle (A) if it is an equation. 1. 2x + 9 =
2. 32 + 3 x 9) = 59
3. 3k + 7 = 34
4.5 (b + 28) = 150
5. 9a + 7 =​

what the question so we can you out

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
