All circles have the same angles, just different degrees
Answer:
C
Step-by-step explanation:
x² + 6x = 18
To complete the square, take the coefficient of the x term, halve it, square the result, then add to both sides.
(6/2)² = 3² = 9
x² + 6x + 9 = 18 + 9
(x + 3)² = 27
x + 3 = ±√27
x = -3 ± √27
Answer:
(-13, -4)
Step-by-step explanation:
It is about as easy to try the solutions as it is to find them from scratch.
__
However, we can determine which one it is by adding twice the second equation to the first.
(-2a +3b) +2(a -4b) = (14) +2(3)
-5b = 20
b = -4 . . . . . . matches the first choice

but why is it fx then the rest r g?
Answer:
x-3y-z
Step-by-step explanation:
separate common terms and add them
1/2x+3/4x=1x
-2y-y=-3y
2z-3z=-1z
1x-3y-1z
