4. The Distributive Property
Continue to next subchapter

Exercise 30 Page 225

Recall the Distributive Property.

C

Practice makes perfect
We are asked to match the given expression with an equivalent expression. First, we will simplify it. To do it, we will use the Distributive Property. We will distribute 6 to the terms inside the parentheses.
6(n+4)
6(n)+6(4)
6n+24

Since 6n and 24 are not like terms, the expression cannot be simplified further. Now let's take a look at the possible equivalent expressions.

Option Expression Is It Equivalent to 6n+24?
A 3(2n+6)  ?
B 6n+9 No
C 3(2n+8)  ?
D 6n+12 No

We can already tell that the expressions B and D are not equivalent to our expression. It is because they are all in simplest forms and they are not the same as our expression! The expressions A and C can be simplified further.

Option Expression Use the Distributive Property Multiply Is It Equivalent to 6n+24?
A 3(2n+6) 3(2n)+3(6) 6n+18 No
C 3(2n+8) 3(2n)+3(8) 6n+24 Yes

We found that the expression from option C is equivalent to the given expression!
