BRAINLIEST Andrew is showing his work in simplifying β4.5 + 4.2 + 5.6 β 7.3. Identify any errors in his work or in his reasoning. Step Work Reasoning β4.5 + 4.2 + 5.6 β 7.3 Original problem 1 β4.5 + 4.2 + 5.6 + (β7.3) Additive inverse 2 β4.5 + (β7.3) + 4.2 + 5.6 Commutative property 3 [β4.5 + (β7.3)] + (4.2 + 5.6) Associative property 4 β11.8 + 9.8 Simplify 5 β21.6 Simplify Step 1: He wrote β7.3 incorrectly as + (β7.3). Step 2: He identified changing the order of the numbers as the commutative property, which is incorrect. Step 3: He identified changing the grouping of the numbers as the associative property, which is incorrect. Step 5: He simplified incorrectly.
