Ineed on 8 and 10 which one do i circle on ten

#8. round to the nearest cent= 0.14

#9.round to the nearest hundredth = 0.28

#10

8.28 , 8.33, 8.25 round to nearest tenth 8.3

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 simply just 6n add the two together as they have an n
