Answer:
Doreen traveled 35 miles.
Step-by-step explanation:
5 to the power of 2 is 25
2 multiplied by 5 is 10
then you add the 2 numbers and you get 35
![{x}^{2} + 4y + 2x + 2xy](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%204y%20%2B%202x%20%2B%202xy)
We can factorise this expression by grouping. First let us arrange it in this way
![= {x}^{2} + 2xy + 2x + 4y](https://tex.z-dn.net/?f=%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202xy%20%2B%202x%20%2B%204y)
Let us bracket them like this:
![= ( {x}^{2} + 2xy) + (2x+ 4y)](https://tex.z-dn.net/?f=%20%3D%20%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%202xy%29%20%2B%20%282x%2B%204y%29)
In the first bracket portion, take x as common and in the second expression, take 2 as common.
![= x(x + 2y) + 2(x + 2y) \\ = (x + 2)(x + 2y)](https://tex.z-dn.net/?f=%20%3D%20x%28x%20%2B%202y%29%20%2B%202%28x%20%2B%202y%29%20%5C%5C%20%20%3D%20%28x%20%2B%202%29%28x%20%2B%202y%29)
<u>Answer</u><u>:</u>
![(x + 2)(x + 2y)](https://tex.z-dn.net/?f=%28x%20%2B%202%29%28x%20%2B%202y%29)
