Aiko is finding the sum (4 + 5i) + (–3 + 7i). she rewrites the sum as (–3 + 7)i + (4 + 5)i. which statement explains the mathematical property that she made an error using?

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.
