Nora is comparing the number of trading cards she has with her friend Kaiden. Originally, Nora had four times as many cards as Kaiden had. She then got eight additional cards for her birthday. If Kaiden had 11 cards when they did their comparison, how many did Nora have after her birthday?

52

Step-by-step explanation:

If Nora had 4 times as many as Kaiden (11) had, then she had 44

After her birthday, she got 8 more (44+8)

44+8=52

Hope this helps! :)

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
