Answer 1

The person above answered it correctly lol! :D

Answer 2

In this problem, we have different expressions involving products, by applying the distributive law for the multiplication we can generate equivalent expressions.

The distributive law for multiplication says that:

`a\cdot(b+c)=a\cdot b+a\cdot c\text{.}`

Example

14. 8 (4x + 9)

By applying the distributive law, we have:

`8\cdot(4x+9)=8\cdot4x+8\cdot9=32x+72.`

Which is an equivalent expression, and it is the answer.

Answer

For point 14, 8 (4x + 9), the answer is 32x + 72.
