Answer: -2b-4
Ok, so I assume you meant b-4-3b. If not, then B-4-3b is the best you can get, since B and b are different in math.
Anyways, we can rearrange b-4-3b into b-3b-4. Calculating b-3b = -2b. That means -2b-4 is the answer.
Hope that helped,

Answer:
B
Step-by-step explanation:
pi / 2 is equal to 180°/2 which is 90°.
Cos (90°) = 0
if cos90 = 0 then what kind of graph will we have at 90° to the x axis ?
a graph passing through the origin. (0,0)
Paula's dog : Carolos' dog = 3 : 1
The total number of ratio units is 3+1 = 4, so each one stands for (48 lb)/4 = 12 lb.
Paula's dog weighs 3·12 lb = 36 lb.
Carlos' dog weighs 1·12 lb = 12 lb.
I got 20,737 but I could be wrong so I will attach my algorithm and work.
Answer:
The sum is 
Step-by-step explanation:
we know that
The formula of the sum in a geometric sequence is equal to
![S=a1[\frac{1-r^{n}}{1-r}]](https://tex.z-dn.net/?f=S%3Da1%5B%5Cfrac%7B1-r%5E%7Bn%7D%7D%7B1-r%7D%5D)
where
a1 is the first term
r is the common ratio
n is the number of terms
we have
a1=-4, a2=24, a3=-144
Find the value of r (common ratio)
r=a2/a1
r=24/(-4)=-6
so
a1=-1
r=--6
n=6
substitute in the formula
![S=(-4)[\frac{1-(-6)^{6}}{1-(-6)}]](https://tex.z-dn.net/?f=S%3D%28-4%29%5B%5Cfrac%7B1-%28-6%29%5E%7B6%7D%7D%7B1-%28-6%29%7D%5D)
![S=(-4)[\frac{1-(-6)^{6}}{7}]](https://tex.z-dn.net/?f=S%3D%28-4%29%5B%5Cfrac%7B1-%28-6%29%5E%7B6%7D%7D%7B7%7D%5D)
