a circles area is represented by a= pie(x^2-22x+121). what expression represents the radius of the circle? a. x+11 b. x-11 c. x-22 d. x+22

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

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
