The answer is 977 seconds squared
Answer:
The first one x =3
Step-by-step explanation:
3-2 = 1
3 +10 = 13
1*13 =13
Answer:
B
Step-by-step explanation:
Okay so the first answer you can't collect data on something you don't know about. B is the correct answer because you need to make observations and identfy the problem. C. You have no results to study if you don't make observations. D. If you don't study and follow the steps theres nothing to tell anyone you discovered
Answer:
a) x= 5 or x= -3
b) x = -4 +
or -4 - ![\sqrt{26}](https://tex.z-dn.net/?f=%5Csqrt%7B26%7D)
Step-by-step explanation:
a)
- 2x - 15 =0
x =
or ![\frac{-(-2) -\sqrt{(-2)^{2} - 4(1)(-15)}}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%28-2%29%20-%5Csqrt%7B%28-2%29%5E%7B2%7D%20-%204%281%29%28-15%29%7D%7D%7B2%281%29%7D)
x= 5 or x=-3
b)
+ 8x - 10 =0
x =
or ![\frac{-(8) -\sqrt{(8)^{2} - 4(1)(-10)}}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%288%29%20-%5Csqrt%7B%288%29%5E%7B2%7D%20-%204%281%29%28-10%29%7D%7D%7B2%281%29%7D)
x = -4 +
or -4 - ![\sqrt{26}](https://tex.z-dn.net/?f=%5Csqrt%7B26%7D)
