Which identity shows that vector addition is associative?
A(a + b) + c = a - (b + c)
B(a - b) - c = a - (b - c)
C(a + b) + c = (a - b) + c
D(a + b) + c = a + (b + c)
Answer & Solution
Correct answer: D. (a + b) + c = a + (b + c)
Associativity means the grouping of three vectors being added does not change the total.
