Final answer:
The expression 3(1.5x+9) is solved using the distributive property, resulting in 4.5x + 27.
Step-by-step explanation:
The question asks us to apply the distributive property to the expression 3(1.5x+9). The distributive property states that for any numbers a, b, and c, the expression a(b+c) is equal to ab + ac. Using this property, we can distribute the 3 to both 1.5x and 9.
Applying the distributive property, we get:
- Multiply 3 by 1.5x to get 4.5x.
- Multiply 3 by 9 to get 27.
- Combine the results to get the final expression: 4.5x + 27.
Therefore, the expression 3(1.5x+9) using the distributive property is 4.5x + 27.
