First, simplify out the brackets:
-20 - 4n = -12
Then, combine like terms by moving the -20 to the other side
-4n = -12 + 20
-4n = 8
Divide by -4 on both sides to isolate the n
n = 8/-4
n = -2
Cross multiply:
30n = 2400. Then n = 80.
Answer:
A bit of a doosy, but bare with me: f*g*h(x) = 
Step-by-step explanation:
So explaining this is a bit awkward as well, but I can try...So
Starting from g(x) working that backwards into f(x), so...
g(x) = 
f(x) = 
Take your g(x) and plug it into your f(x) into every x you see
f(g(x)) =
~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...
Now you still have one more step which you still need to include h(x), so
Remember h(x) = 
Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

Answer:
C is greater
D is less
Step-by-step explanation:
Answer:
(B) x=2
Step-by-step explanation:
4(x + 6) - 3x = 26
4x+24-3x=26
x+24=26
Subtarct 24 from both sides
x=2
