Actually Welcome to the Concept of the Functions. 
Let's first find the g(-1),
so we get as 
3(-1)^2 +5(-1)-6
=> 3 -5-6
=> -8 
now since g(-1) =-8 
let's find f(g(-1)) that is f(-8)
f(-8) = 4(-8) + 14
=> f(g(-1)) = -32+14 
=> f(g(-1)) = -18 
-18 is the answer.
 
        
             
        
        
        
Answer:
 -3 the reaction force will be 3, the net force will have to add up to 0.
Step-by-step explanation:
 
        
             
        
        
        
X-2=0
x=2
into the eqn:(2)cube +k(2)+1= -3
2k = -12 
k=-6
        
             
        
        
        
Answer:
∠1 is 130°
∠2 is 50°
∠3 is 130°
Step-by-step explanation:
The 50° is congruent to ∠2 which makes it 50°.  The remaining angles must add up to 180 on each side in which 130° is your appropriate answers for ∠1 and ∠3.
 
        
             
        
        
        
Answer:
1. 4(.8)-3.5= 3.2-3.5= -0.3
2. 3(3)--5(5)-9(-1)= 9 - 25 + 9 = 18 - 25= -7
