Which of the following uses the distributive property correctly? 3(x + 5) = 3 • x - 3 • 5 3(x + 5) = 3 • x + 5 3(x + 5) = 3 • x + 3 • 5 3(x + 5) = 3 + 3 • 5

3(x+5) = 3x + 3*5             or simplified (3x + 15)

Step-by-step explanation:

Distributive property states that if a,b and c are three elements then,

a(b+c)= ab+ac

Let a=3

b= x

and c=5

then, above property can be written as:

3(x+5)=3.x+3.5

Hence, Distributive property is used correctly in:

3(x + 5) = 3 • x + 3 • 5
