The statement p
q represents "if a number is doubled, the result is even
which represents the inverse?
- -- where p = a number is doubled and q = the result is even
9-p where p = a number is doubled and the result is even
where p = the result is even and q = a number is doubled
9-p where p = the result is even and q = a number is doubled

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

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
