$10 y + 15$ $10y + 15$

To expand this you need to multiply each term inside the parenthesis by the term outside the parenthesis, in case $5$ $5$ :

$5 (2 y + 3) \Rightarrow (5 \cdot 2 y) + (5 \cdot 3) \Rightarrow 10 y + 15$ $5(2y + 3) => (5 * 2y) + (5 * 3) => 10y + 15$

How do you expand 5(2y+3)5(2y+3)5(2y+3)?
