Hey there!
Assuming you meant
![5r^2 - 12 = 68](https://tex.z-dn.net/?f=%205r%5E2%20-%2012%20%3D%2068%20%20)
If so, follow these steps so it can be a little bit easier to solve
Firstly, we have to
by
on each of your sides
![5r^2 -12 +12 \\ \\ 68 + 12](https://tex.z-dn.net/?f=%205r%5E2%20-12%20%2B12%20%5C%5C%20%5C%5C%2068%20%2B%2012%20%20)
![5r^2 = 5r^2 \\ \\ 68 + 12 = 80](https://tex.z-dn.net/?f=%205r%5E2%20%3D%205r%5E2%20%5C%5C%20%5C%5C%2068%20%2B%2012%20%3D%2080%20%20)
We get: ![5r^2 =80](https://tex.z-dn.net/?f=%205r%5E2%20%3D80%20%20)
Now, we have
by
on each of your sides
![\frac{5r^2}{5} = \frac{80}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5r%5E2%7D%7B5%7D%20%3D%20%5Cfrac%7B80%7D%7B5%7D%20%20)
![\frac{80}{5} = 16](https://tex.z-dn.net/?f=%20%5Cfrac%7B80%7D%7B5%7D%20%20%3D%2016%20%20)
We get: ![r^2 = 16](https://tex.z-dn.net/?f=%20r%5E2%20%3D%2016%20%20)
± ![\sqrt{16}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20%20)
Therefore , your answer is:
±![4](https://tex.z-dn.net/?f=%204%20%20)
Good luck on your assignment and enjoy your day!

Answer:
b, 1 5/8
Step-by-step explanation:
the area is 4 15/32 square meters, and you find the area by doing length x width. the length is provided, 2 3/4. so all you have to do is divide 4 15/32 by 2 3/4 and you get 1 5/8
Answer:
y=|x-1|-1
Step-by-step explanation:
hope that helps :)
Answer:44
Step-by-step explanation: 60/5 evaluates to 12
Multiply 3 and 12
1
3*(60/5) evaluates to 36
8+3*(60/5) evaluates to 44
Answer:
c
Step-by-step explanation:
mass will never change only weight will as weight is dependent on gravitational field strength
