Which equation demonstrates the distributive property? a) 14 + 77 = 91 b) 14 x 77 = 77 x 14 c) 14 + 77 = 7(2 + 11) d) (2 + 11)7 = 7(2 + 11)

A) 14 + 77 = 91 - it's the sum

B) 14 × 77 = 77 × 14 - it's a commutative property a × b = b × a

C) 14 + 77 = 7(2 + 11) - it's a distributive property a(b + c) = ab + ac

D) (2 + 11)7 = 7(2 + 11) - it's a commutative property a × b = b × a
