Answer:
One solution
Step-by-step explanation:
Expanding the equation, we get
-2w-12-6w=4w+12
Subtracting 4w from both sides, we get
-12w-12=12
Now adding 12 to both sides,
-12w=24
Solving for w, we get
w=-2
So there is only one solution to the equation.
Common ratio = 22/-11 = -2 also -76 / 88 = -2 confirms it.
B/ a0 = -11 / -2 = 5.5 and a1 = 88 / -2 = -44
