Answer:
Equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Step-by-step explanation:
The distributive property says that:
![a \cdot (b+c) = a\cdot b + a\cdot c](https://tex.z-dn.net/?f=a%20%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%20%2B%20a%5Ccdot%20c)
Given the expression: ![9(2a+1)](https://tex.z-dn.net/?f=9%282a%2B1%29)
Apply the distributive property:
![9 \cdot (2a) +9 \cdot 1](https://tex.z-dn.net/?f=9%20%5Ccdot%20%282a%29%20%2B9%20%5Ccdot%201)
Simplify:
![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Therefore, the equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
