Which property justifies the following statement?
konstantin123 [22]

Answer:

Distributive Property

Step-by-step explanation:

If the given statement is

5(72 – 3y) = 360– 15y

When we apply the distributive property to the left hand side we get;

5(72 - 3y) = 5 \times 72 - 5 \times 3y

When we simplify we get

5(72 - 3y) =360- 15y

Therefore the distributive property justifies the given statement.
