<span>Multiplying with 6 is a mathematical process similar to multiplying with 3, in that setting up the greatest common factors between the two is easy due to the fact that 6 is a multiple of 3. As 6 is simply 3 doubled, any multiple of 6 will be the relative multiplation for 3 doubled. </span>

Answer:
Step-by-step explanation:
circle A is
x²+y²+6x-4y-12=0
x²+6x +y²-4y =12
think (a+b)² = a²+2ab+b² we have a=x, b= 3
and (a-b)² = a²-2ab+b² so we have a=y, b=2
x²+6x +9 +y²-4y+4 = 12-9-4
(x+3)² +(y-2)²= -1
compare to the general equation of a circle (x-h)²+(y-k)² =r²
the center is at (-3,2) and the radius is √-1 =i
Circle B has center (0, -4) and radius 3 so the equation is
(x-0)²+(y-(-4))² =3²
x² +(y+4)² = 9
point (√8, -3) is on the circle if it verifies the equation
√8² +(-3+4)² = 9
8+1 =9 true so the point is on the circle
Circle A and circle B are not similar because they do not have the same center and radius
Answer:
D
Step-by-step explanation:

Sin x = 32/58
sin x = .5517
x = 33°
I found 3 sides and muliplied the answer by 2 because there are 6 sides.
60+108+45=213
213 x 2 = 426 m squared.
