Answer:
![\boxed{\sf{15x+30}}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/cgzepezbj9kob4rg5tf88fvux0nkksydxu.png)
Explanation:
It is only necessary to use the distributive property to solve this problem.
Distributive property:
![\sf{A(B+C)=AB+AC}](https://img.qammunity.org/2023/formulas/mathematics/high-school/zk8taw7krsfs4twlsndis2zjp6iytxl8n2.png)
5(3x+6)
![\sf{5\left(3x+6\right)=5*3x+5*6}](https://img.qammunity.org/2023/formulas/mathematics/high-school/p3odiy0maoar7kt7qfo9ouzrbsyqigjvk3.png)
Then, solve.
5*3=15
5*6=30
= 15x+30
To get the correct answer, don't forget to include the variable.
So, the correct answer is 15x+30.
