Ada is showing her work in simplifying (5.9 − 1.8) − 6.2 + 4.1. in which step did ada make an error?

step 1: (5.9 − 1.8) − 6.2 + 4.1

step 2: 5.9 + (−1.8 − 6.2) + 4.1 (associative property)

step 3: 5.9 − 8 + 4.1

step 4: 5.9 + 4.1 − 8 (associative property)

step 5: 10 − 8 = 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.
