Answer:
![(14 + 7) + 12 = 14 + (7 + 12)](https://tex.z-dn.net/?f=%2814%20%2B%207%29%20%2B%2012%20%3D%2014%20%2B%20%287%20%2B%2012%29)

Select equivalent expression
![(14 + 7) + 12](https://tex.z-dn.net/?f=%2814%20%2B%207%29%20%2B%2012)
Associative property states that:
![(a + b) + c = a + (b + c)](https://tex.z-dn.net/?f=%28a%20%2B%20b%29%20%2B%20c%20%3D%20a%20%2B%20%28b%20%2B%20c%29)
In this case:
![a = 14](https://tex.z-dn.net/?f=a%20%3D%2014)
![b = 7](https://tex.z-dn.net/?f=b%20%3D%207)
![c = 12](https://tex.z-dn.net/?f=c%20%3D%2012)
So, we have:
![(a + b) + c = a + (b + c)](https://tex.z-dn.net/?f=%28a%20%2B%20b%29%20%2B%20c%20%3D%20a%20%2B%20%28b%20%2B%20c%29)
![(14 + 7) + 12 = 14 + (7 + 12)](https://tex.z-dn.net/?f=%2814%20%2B%207%29%20%2B%2012%20%3D%2014%20%2B%20%287%20%2B%2012%29)
B. is correct
Answer:
9/10p
Step-by-step explanation:
1/2p+ 2/5 p
Get a common denominator of 10
1/2 p *5/5 = 5/10 p
2/5p *2/2 = 4/10 p
1/2p * 2/5 p
5/10p * 4/10 p
9/10p
Answer:
4.5 cm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
121.5 pi = 4/3 pi r^3
Divide each side by pi
121.5 = 4/3 r^3
Multiply each side by 3/4
3/4 *121.5 = 3/4 * 4/3 r^3
91.125 = r^3
Take the cube root of each side
(91.125)^ (1/3) = r^3 ^(1/3)
4.5 = r
