Answer:
Option D is correct.
Distributive Property.
Step-by-step explanation:
The distributive property says that:
[tex]a \cdot (b+c) = a\cdot b + a\cdot c[/tex]
Given the expression:
[tex]12(x+4)[/tex]
which represents the total cost of CDs Mei bought in April and May at $12 each.
[tex]12(x+4)[/tex]
Using distributive property, we have;
[tex]12 \cdot x + 12 \cdot 4[/tex]
Simplify:
12x + 48
Therefore, the property which is applied to write the equivalent expression 12x+ 48 is, distributive property
