Answer:
A i think bc its the only one that makes since
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. So therefore, the numbers would be 2 and 4.
14+14=28
48-28=20
20 divided by 2 =10
The width is 10
Answer:

Step-by-step explanation:
We have

and

We want to find (f+g)(x).
By the algebraic properties of polynomial functions,


This simplifies to

We can't simplify further, hence the simplest form
