Answer:
The answer is 204
Step-by-step explanation:
34×6=204
(7^2)x = 1
x = 1/(7^2) = 7^(-2).
You obtain the value of x by dividing both sides by 7^2 and the inverse of 7^2 is 7^(-2).

Answer:
B. x² +y² = 18
Step-by-step explanation:
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
For (h, k) = (0, 0) and r = 3√2, the equation is ...
(x -0)² +(y -0)² = (3√2)² = 3²·2
x² +y² = 18
