triangle a″b″c″ is formed by a reflection over x = −3 and dilation by a scale factor of 3 from the origin. which equation shows the correct relationship between δabc and δa″b″c′?

The correct relationship  is,

Step-by-step explanation:

The correct relationship is,

Since, the ΔA''B''C'' is formed from ΔABC by a reflection over x = -3 and dilation by a scale factor of 3 from the origin ,so , the two triangles will be similar, or, ΔA''B''C''  ΔABC .

So, their corresponding sides will be in the same ratio, i. e. 3 : 1 .
