Determine if there is a proportional relationship between the two quantities. explain your reasoning.

Two quantities are proportional if their ratio is constant. Let's check the ratios:

So, the two quantities appear to be proportional, and the constant seems to be 2.5.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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
