Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the mathema tical property that she made an error using?
2 answers:
Answer: The Distributive Property Aiko didn't seem to realize that rewriting it like that would cause the expression to have a different solution. She should study her math.
Answer:
Given the expression :
Aiko rewrites the equation by factoring out the from the expression and this wrote it as,
but this is wrong because is an imaginary number which is with a number 5 and 7.
Therefore, Aiko cannot factor out the because it is not present in both numbers -3 and 4
She could rewrote it as
So, she incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.
