Answer:
The simplified answer is 20x + 15
Explanation:
The first and only step we have to do here is distributive property.
Distributive property means to multiply the number outside the parentheses to all of the numbers inside the parentheses.
Such as 5 × 4x and 5 × 3
Then we keep the sign that was in the parentheses and plug in your answers
so 20x + 15
