PLS HELP 4 4/12 - 2 11/12

A. 2 5/12

B. 2 7/12

C. 1 5/12

D. 1 7/12

2 7/12 B

Step-by-step explanation:

5x+2x=49

7x=49

x=7. 35 apples

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
