Answer 2

Step-by-step explanation:

Combining like terms is used in math in order to simplify expressions. We combine common terms in order to make the expression much easier. Common terms are those that have the same variable and exponent. So in the expression:

`3.26d+9.75d-2.65 \\ \\ \\ So: \\ \\ \text{The terms} \ 3.26d, \ 9.75d \ \text{have the same variable d and exponent 1} \\ \text{therefore we can combine them}`

Thus, the expression becomes:

`3.26d+9.75d-2.65=(3.26d+9.75d)-2.65=\boxed{13.01d-2.65}`
