You can do this by comparing your equation to the general form of equation of a circle
( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9
so (a,b) = (-9,-6) and r = 3
so the answer is B
Answer:
first one : (7+12+3+4+4+8)*2=76
For this case we can make use of the Pythagorean theorem.
We have then:
(root (117)) ^ 2 = x ^ 2 + 6 ^ 2
Clearing x we have:
x ^ 2 = (root (117)) ^ 2 - 6 ^ 2
Rewriting:
x = root (117-36)
x = root (81)
x = 9
Answer:
The value of x is given by:
x = 9 cm
Answer:
you would only need to add or multiply the numbers
Step-by-step explanation:
some of the equations could be-
95+ x =190
95 x 2 =190
x / 2 = 190
Answer:
3 times
Step-by-step explanation:
divide both numbers Which will give you 3
