Susan recorded an outside temperature of −7°C at 9:00 a. M. She recorded the outside temperature again at 4:00 p. M. When the temperature reading showed the opposite value. Which was Susan's temperature reading at 4:00 p. M.?

7°C is the answer cause its the opposite value of −7°C

Step-by-step explanation:

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

the answer is stop cheating on things stoopid
