1. The problem asks us to describe parts of the expression $4(8x + 5)$.\n\n2. The entire expression $4(8x + 5)$ is the product of two parts: the number 4 and the sum inside the parentheses $(8x + 5)$.\n\n3. The sum inside the parentheses $(8x + 5)$ consists of two terms: $8x$ and $5$.\n\n4. So, the entire expression is the product of the number 4 and the sum $(8x + 5)$.\n\n5. On its own, $(8x + 5)$ is a sum with two terms: $8x$ and $5$.\n\n6. To summarize:\n- The entire expression is the product of 4 and the sum $(8x + 5)$.\n- The sum $(8x + 5)$ has two terms: $8x$ and $5$.
