Question

9) When solving, here is the First Step: 3(x + 5) = 3x + 15

The property used was
a) The associative property
c) The distributive property
b) The commutative property
d) The addition property of equality

Answer 1

The distributive property is used in this equation to simplify it.

Step-by-step explanation:

The property used in this equation is the distributive property. The distributive property states that when multiplying a number by a sum or difference, you can distribute the multiplication to each term inside the parentheses. In this case, the 3 outside the parentheses is being multiplied by both x and 5. So, the equation becomes 3 * x + 3 * 5 = 3x + 15. This step simplifies the equation and allows for further solving.
