Answer:
so whats the question?
Step-by-step explanation:
Answer:
x=-7
x=7
Step-by-step explanation:
we have
![2x^{2}-98=0](https://tex.z-dn.net/?f=2x%5E%7B2%7D-98%3D0)
Solve for x
Adds 98 both sides
![2x^{2}-98+98=0+98](https://tex.z-dn.net/?f=2x%5E%7B2%7D-98%2B98%3D0%2B98)
![2x^{2}=98](https://tex.z-dn.net/?f=2x%5E%7B2%7D%3D98)
Divide by 2 both sides
![2x^{2}/2=98/2](https://tex.z-dn.net/?f=2x%5E%7B2%7D%2F2%3D98%2F2)
![x^{2}=49](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D49)
take square root both sides
![x=\pm7](https://tex.z-dn.net/?f=x%3D%5Cpm7)
therefore
The solutions are
x=-7
x=7
Answer: The second one, “A rabbit jumps 2 feet. A kangaroo jumps 16 feet. The kangaroo jumps 8 times as far as the rabbit
Step-by-step explanation:
2/3 lost is 1/3 kept
2/3 of the 1/3 kept is 2/9 lost
1/3 x - 2/9 x = 4
3/9 x - 2/9 x = 4
1/9 x = 4
x = 36
First she lost 2/3 of 36, which is 24. She had 12 left. Then she lost 2/3 of 12 which is 8. She had 4 left.

66 is the outlier because it is less than all the other numbers while all the numbers are in the 70s and 80s
