Final answer:
In the expression 724 - 5 + 10 (y + 5), the term (y + 5) is the correct factor as it is the part of the expression being multiplied by 10, which makes option D the right answer.
Step-by-step explanation:
To find which of the given options is a factor in the expression 724 - 5 + 10 (y + 5), we need to identify the parts of the expression that are multiplied together. A factor is a term that is multiplied by another term within an expression.
Looking at the expression, we can see that 10 is being multiplied by (y + 5), so the correct factor is (y + 5). Therefore, option D is the factor of the given expression. None of the other options represents a term that is multiplied by another term in the expression in their entirety.
Let's examine why the other options are not factors:
- Option A: 724 - 5 is a subtraction, not a multiplication.
- Option B: While -5 + 10 (y + 5) includes the multiplication of factors, it is not itself just a factor.
- Option C: This option is not present in the correct form within the expression.
