Answer:
Area of the walkway = 8<em>x </em>+ 24
Step-by-step explanation:
Area of the total backyard = ![l\times b](https://tex.z-dn.net/?f=l%5Ctimes%20b)
Area of total backyard = ![(x+6)\times (x+4) = x^{2} +10x + 24](https://tex.z-dn.net/?f=%28x%2B6%29%5Ctimes%20%28x%2B4%29%20%3D%20x%5E%7B2%7D%20%2B10x%20%2B%2024)
Now, Area of the rectangular garden = ![l\times b](https://tex.z-dn.net/?f=l%5Ctimes%20b)
Area of the rectangular garden = ![x (x+2) = x^{2} + 2x](https://tex.z-dn.net/?f=x%20%28x%2B2%29%20%3D%20x%5E%7B2%7D%20%2B%202x)
Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden
= ![(x^{2} +10x +24) - (x^{2} +2x)](https://tex.z-dn.net/?f=%28x%5E%7B2%7D%20%2B10x%20%2B24%29%20-%20%28x%5E%7B2%7D%20%2B2x%29)
= ![x^{2} + 10x +24 - x^{2} -2x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%2010x%20%2B24%20-%20x%5E%7B2%7D%20-2x)
= 8<em>x</em> + 24
Answer:14/15
Step-by-step explanation:
