Question

Which statement illustrates the distributive property?

A. 9(51 - 12) = 9(51) – 121
OB. 9(5i +121) = 9(121 + 51)
OC. 9(51 – 12) = 9(51) — 9(121)
OD
9 + (51 – 12i) = (9 +51) - (9 + 121)

Answer 1

Answer: Choice C

9(51-12) = 9(51) - 9(12)

============================================

Step-by-step explanation:

The distributive property is

a(b+c) = a*b + a*c

which can also be written as

a(b-c) = a*b + a*(-c) = a*b - a*c

In this case we're using

a(b-c) = a*b - a*c

where a = 9, b = 51, c = 12
