Explanation:
For this exercise it is important to remember the following:
1. By definition, the "Product" is the result of a multiplication.
2. The "Difference" is defined as the result of a subtraction.
3. The Distributive property states that:
![a(b+c)=ab+ac\\\\a(b-c)=ab-ac](https://img.qammunity.org/2021/formulas/mathematics/middle-school/klwplrt396wh5j1if59xl3dimm1c5v2oyc.png)
Keeping the above on mind, you know that:
"The difference of
and
" can be represented with the following expression:
![c-d](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yxpd1dgqbkk7wscqt4nmn1iyl5f3ww8ll8.png)
Therefore, "The product of -13 and the difference of
and
" can be represented with this expression:
![-13(c-d)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/uva3y7dvk3jagoq7ifwktncf7grj68bkqc.png)
Finally, you must apply the Distributive property in order to simplify the expression. You get:
![=-13c+13d](https://img.qammunity.org/2021/formulas/mathematics/middle-school/o2sb2spucy2l0uhexrp468c0nnjcupons3.png)
