Question

Identify the properties needed to prove n + n + n + 2n = 5n.

Place the valid properties in the Valid box, and place the invalid properties in the Invalid box.
Distributive Property
n(1 + 1 + 1 + 2)
Distributive Property
1(n + 2n)
Associative Property
n • 5 = 5n
Multiplicative Identity
0 • n + 0 • n + 0 • n + 2 • n
Commutative Property
n • 5 = 5n
Multiplicative Identity
1 • n + 1 • n + 1 • n + 2 • n

Answer 1

just type in valid or invalid
