Solving expression
we get ![12x+30y](https://tex.z-dn.net/?f=12x%2B30y)
Step-by-step explanation:
We need to solve the expression:
![2x+5y+5(2x+5y)](https://tex.z-dn.net/?f=2x%2B5y%2B5%282x%2B5y%29)
Solving:
Multiplying 5 with terms inside the bracket:
![2x+5y+5(2x+5y)\\=2x+5y+10x+25y\\Combining\,\,like\,\,terms:\\=2x+10x+5y+25y\\=12x+30y](https://tex.z-dn.net/?f=2x%2B5y%2B5%282x%2B5y%29%5C%5C%3D2x%2B5y%2B10x%2B25y%5C%5CCombining%5C%2C%5C%2Clike%5C%2C%5C%2Cterms%3A%5C%5C%3D2x%2B10x%2B5y%2B25y%5C%5C%3D12x%2B30y)

Answer:
2 cm, 9 cm, 10 cm
Step-by-step explanation:
To know if a combination is a triangle all you have to do is see if the combinations add up to 180
(2)(9)(10)=180 therefore it is a triangle.
All the other angles do not add up to 180 so they can't be triangles!!
(4)(10)(3)
=120
(5)(6)(11)
=330
(4)(5)(7)
=140
