1. The problem is to represent the expression $5(x+3)$ pictorially. 2. This expression means 5 times the quantity $(x+3)$. 3. To visualize this, imagine a group containing $x$ units and 3 units, and then you have 5 such groups. 4. So, you can think of it as 5 groups, each with $x$ items plus 3 items. 5. This can be drawn as 5 boxes, each containing $x$ dots and 3 dots. 6. The total number of dots is $5 \times (x+3)$, which simplifies to $5x + 15$. 7. This pictorial representation helps understand the distributive property: $a(b+c) = ab + ac$. Final answer: The expression $5(x+3)$ represents 5 groups of $(x+3)$ items, which equals $5x + 15$.
