b. 3.x +5x-1
c. 5+2+7+4.0
d. 4- 2x + 5.0
e. 10. - 5+ 3.1 -- 2

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
