Question

Please, someone, help me with this MATH question.

Answer 1

`3(5+x)=15+3x`, first option

Explanation:

The distributive property lets us multiply a parentheses by its coefficient. For example:

`4(x+3)=`

`4*x + 3*4=`

`4x+12`

Apply this theory to this problem.

`3(5+x) =`

`3*5+3*x=`

`15+3x`

Thus, the answer is the first option,
`3(5+x)=15+3x`
