Derek adds water to a pool at a rate of 12 gallons per minute send then reduces the rate 8 gallons per minute. Derek adds water to the pool for a total of 2 hours. let t be the time in hours that he adds water to the pool at the faster rate. Write a algebraic expression to represent how many minutes he adds water to the pool at each rate.

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

english, cause i can’t you
