Answer:
1) Av2O2 N.Stook: peróxido de oro (I) N.Sistemática: dióxido de dioro N.Tradicional: perioxido auroso
Answer: The correct answer is number 4.
Step-by-step explanation: First, solve the (). 7x + x or 7x + 1x = 8x. Now, you have 4(8x + 2). That would be the first choice, A. But what about the second one? Well, 4 x 8x would be 32x, and 4 x 2 would be 8. Now put that together. 32x + 8. Is there an expression like that? Yes, there is. Choice C. Now that means choice A and C are equivalent to 4(7x + 2 + x). Only number 4 holds those choices, so your answer would be number 4. Hope this helped! :)
Answer:
For a polynomial of the form
ax2+bx+c, rewrite the middle term as a sum of two terms whose product is a⋅ c=4−5=−20 and whose sum is b=8.

Answer:
Step-by-step explanation:
1) Separate terms with roots from terms without roots.
![x^2+4=\sqrt[\frac{1}{2} ]{4+1}](https://tex.z-dn.net/?f=x%5E2%2B4%3D%5Csqrt%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%7B4%2B1%7D)
2) Simplify 4 + 1 to 5.
![x^2+4=\sqrt[\frac{1}{2} ]{5}](https://tex.z-dn.net/?f=x%5E2%2B4%3D%5Csqrt%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%7B5%7D)
3) Invert and multiply.
4) Simplify 
to 25.
5) Subtract 4 from both sides.
6) Simplify 25 - 1 to 24.
7) Take the square root of both sides.
