Write an algebraic expression for the phrase. the sum of b and 11

The correct answer is: 11+b

In this case is a variable.

11 is a number.

Since it is asking for the sum then that means you must add those two together.

This means that the sum of 11 and means that you have to add the two factors.

Therefore, the sum of and 11 is:

11 +

Hope this helps! :3

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
