Answer:
955
Step-by-step explanation:
![9.55 \times {10}^{2} \\ = 9.55 \times 100 \\ = 955](https://tex.z-dn.net/?f=9.55%20%5Ctimes%20%20%7B10%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%209.55%20%5Ctimes%20100%20%5C%5C%20%20%3D%20955)
Answer:
Correct
Step-by-step explanation:
Everything seems correct. I would just put the two answers for questions 3 & 4 in the separate boxes, instead of having two answers in each box.
2x^2 +6x -3. if we are using the quadratic equation this would be
![- 6](https://tex.z-dn.net/?f=%20-%206)
+ or -
![\sqrt{{6}^{2} - 4 \times 2 \times ( - 3) }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%7B6%7D%5E%7B2%7D%20-%204%20%5Ctimes%202%20%5Ctimes%20%28%20-%203%29%20%7D%20)
all over 2×2
this simplifies to
![x = - \frac{3}{2} + \frac{ \sqrt{15} }{2}](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20%20%2B%20%20%5Cfrac%7B%20%5Csqrt%7B15%7D%20%7D%7B2%7D%20)
and
![x = - \frac{3}{2} - \frac{ \sqrt{15} }{2}](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20%20%20-%20%20%20%5Cfrac%7B%20%5Csqrt%7B15%7D%20%7D%7B2%7D%20)
30 12/25 just figure out the fraction for the decimal. heres a website to help u https://www.calculator.net/fraction-calculator.html
One way is to square both numbers. You get 9 and 16.
All the whole numbers between those is 10, 11, 12, 13, 14, and 15.
The square root of each of those numbers will be irrational and between 3 & 4.
Hope this helps!
