I believe the answer would be C.
9^2 = 2x^2
81 = 2x^2
40.5 = x^2
6.36 = x
I think the side length of the square would be around 6.36 cm.
**i don’t know if this is right
Answer:
{4 + 2√3, 4 - 2√3} thus the solution is A. x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)
Step-by-step explanation:
Solve for x over the real numbers:
(x - 4)^2 = 12
Take the square root of both sides:
x - 4 = 2 sqrt(3) or x - 4 = -2 sqrt(3)
Add 4 to both sides:
x = 4 + 2 sqrt(3) or x - 4 = -2 sqrt(3)
Add 4 to both sides:
Answer: x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)

Answer:
![\sqrt{85}](https://tex.z-dn.net/?f=%5Csqrt%7B85%7D)
Step-by-step explanation:
To calculate the distance (d) use the distance formula
d = √ (x₂ - x₁ )² + ( y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)
d = ![\sqrt{(6+1)^2+(-2-4)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%286%2B1%29%5E2%2B%28-2-4%29%5E2%7D)
= ![\sqrt{7^2+(-6)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B7%5E2%2B%28-6%29%5E2%7D)
