Answer:
B
Step-by-step explanation:
![{18}^{2} = {x}^{2} + {x}^{2} \\ \frac{18 \times 18}{2} = {x}^{2} \\ x = \sqrt{9 \times 18} \\ x = \sqrt{9 \times 9 \times 2} \\ x = 9 \sqrt{2}](https://tex.z-dn.net/?f=%20%7B18%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7Bx%7D%5E%7B2%7D%20%5C%5C%20%20%5Cfrac%7B18%20%5Ctimes%2018%7D%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%5C%5C%20x%20%3D%20%20%5Csqrt%7B9%20%5Ctimes%2018%7D%20%20%5C%5C%20x%20%3D%20%20%5Csqrt%7B9%20%5Ctimes%209%20%5Ctimes%202%7D%20%20%5C%5C%20x%20%3D%209%20%5Csqrt%7B2%7D%20)
Answer:
22cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 22/7
r = 3.5
Circumference of a circle = 2 × (22/7) × 3.5
Circumference of a circle = 22cm.
Answer:
x = +-sqrt(3) and they are the actual solutions
Step-by-step explanation:
x^2/ (2x-6) = 9/(6x-18)
get a common denominator of 6x-18
x^2/ (2x-6) * 3/3 = 9/(6x-18)
3x^2/ (6x-18) = 9/(6x-18)
since the denominators are the same, the numerators must be the same
3x^2 = 9
divide by 3 on each side
x^2 = 3
take the square root of each side
sqrt(x^2) = +-sqrt(3)
x = +-sqrt(3)
