Part A Consider this sequence of transformations performed on shape : a dilation by a scale factor of 2, followed by a reflection across the x-axis, and
then a translation left 1 unit. Does the sequence prove that shapes I and IV are similar? Explain your answer.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
