24.48 / 24 = 1.02
24.97/24.48 = 1.02
25.47 / 24.97 = 1.02
Common ratio - 1.02

60.96cm
Step-by-step explanation:
I'll give you a hint. A whole number is not negative. (I think 0 is not whole as well)
Answer:
B) x^2y + 7
Step-by-step explanation:
we are given
![2x^2y^4-10x^2y+14y^3-70](https://tex.z-dn.net/?f=2x%5E2y%5E4-10x%5E2y%2B14y%5E3-70)
We can use grouping method to factor it
![(2x^2y^4-10x^2y)+(14y^3-70)](https://tex.z-dn.net/?f=%282x%5E2y%5E4-10x%5E2y%29%2B%2814y%5E3-70%29)
![(2x^2y\times y^3-5\times 2x^2y)+(14y^3-14\times 5)](https://tex.z-dn.net/?f=%282x%5E2y%5Ctimes%20y%5E3-5%5Ctimes%202x%5E2y%29%2B%2814y%5E3-14%5Ctimes%205%29)
now, we can factor common terms
![2x^2y(y^3-5)+14(y^3-5)](https://tex.z-dn.net/?f=2x%5E2y%28y%5E3-5%29%2B14%28y%5E3-5%29)
![(y^3-5)(2x^2y+14)](https://tex.z-dn.net/?f=%28y%5E3-5%29%282x%5E2y%2B14%29)
so, we get
![2x^2y^4-10x^2y+14y^3-70=(y^3-5)(2x^2y+14)](https://tex.z-dn.net/?f=2x%5E2y%5E4-10x%5E2y%2B14y%5E3-70%3D%28y%5E3-5%29%282x%5E2y%2B14%29)
![2x^2y^4-10x^2y+14y^3-70=(y^3-5)2(x^2y+7)](https://tex.z-dn.net/?f=2x%5E2y%5E4-10x%5E2y%2B14y%5E3-70%3D%28y%5E3-5%292%28x%5E2y%2B7%29)
![2x^2y^4-10x^2y+14y^3-70=2(y^3-5)(x^2y+7)](https://tex.z-dn.net/?f=2x%5E2y%5E4-10x%5E2y%2B14y%5E3-70%3D2%28y%5E3-5%29%28x%5E2y%2B7%29)
we can see that x^2y+7 is one of factor
