Question

Aiko is finding the sum (4 5i) (–3 7i). She rewrites the sum as (–3 7)i (4 5)i. Which statement explains the error Aiko made by using a mathematical property incorrectly?.

Answer 1

Distribute Property

Explanation:

In the first expression, 7 is the only coefficient of i in the second term, and 5 is the only coefficient of i in the first term. The rewritten sum would simplify to -3i +7i +4i+5i.
