Question

Which equation shows an example of the associative property of addition?
(–4 + i) + 4i = –4 + (i + 4i)
(–4 + i) + 4i = 4i + (–4i + i)
4i × (–4i + i) = (4i – 4i) + (4i × i)
(–4i + i) + 0 = (–4i + i)

Answer 1

(–4 + i) + 4i = –4 + (i + 4i)

Reason: the associative property of addition says (a + b) + c = a + (b + c). Here a = –4, b = i, c = 4i, so the first equation matches that pattern.
