we have
![x^{2}-8x=3](https://tex.z-dn.net/?f=%20x%5E%7B2%7D-8x%3D3%20%20)
Complete the square. Remember to balance the equation by adding the same constants to each side
![x^{2}-8x+16=3+16](https://tex.z-dn.net/?f=%20x%5E%7B2%7D-8x%2B16%3D3%2B16%20%20)
![x^{2}-8x+16=19](https://tex.z-dn.net/?f=%20x%5E%7B2%7D-8x%2B16%3D19%20)
Rewrite as perfect squares
![(x-4)^{2}=19](https://tex.z-dn.net/?f=%20%28x-4%29%5E%7B2%7D%3D19%20)
![(x-4)^{2}=19\\ (x-4)=(+/-)\sqrt{19} \\ \\ x1=4+\sqrt{19} =8.359\\ x2=4-\sqrt{19} =-0.359](https://tex.z-dn.net/?f=%20%28x-4%29%5E%7B2%7D%3D19%5C%5C%20%28x-4%29%3D%28%2B%2F-%29%5Csqrt%7B19%7D%20%5C%5C%20%5C%5C%20x1%3D4%2B%5Csqrt%7B19%7D%20%3D8.359%5C%5C%20x2%3D4-%5Csqrt%7B19%7D%20%3D-0.359%20)
therefore
the answer is
![x1=4+\sqrt{19} =8.359\\x2=4-\sqrt{19} =-0.359](https://tex.z-dn.net/?f=%20x1%3D4%2B%5Csqrt%7B19%7D%20%3D8.359%5C%5Cx2%3D4-%5Csqrt%7B19%7D%20%3D-0.359%20%20)
Answer:
a¹⁸b²⁴c⁵⁴
Step-by-step explanation:
(aᵇ)ᶜ = aᵇᶜ = aᵇ×ᶜ
(-aⁿ)ᵒᵈᵈ = -aⁿ
(-aⁿ)ᵉᵛᵉⁿ = aⁿ
aⁿ × aⁿ = aⁿ⁺ⁿ
_________
In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.
so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = <em>a¹⁸b²⁴c⁵⁴</em>

Given X = {15, 22, 33, 44, 89, 165, 1025} and Y = {-5, 15, 33, 88, 99, 150, 160, 1025}, which of the following statements is fal
oee [108]
Answer:
Step-by-step explanation:
Let's suppose it's a c). Ø (X Y). So X Y= X U Y ={-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025}. (X Y)=Ø is the wrong statement.
