Question

I need help with the problem I post as a picture.

Answer 1

Given:

The expression is given as 15x + 3.

The objective is to find the equivalent expression.

Expression:

The general distributive property is,

`(ab+a)=a(b+1)`

Using the distributive property, the given expression can be written as,

`15x+3=3(5x+1)`

Thus, the expression is obtained as 3(5x + 1).

Hence, option (C) is the correct answer.
