Answer:
f(g) = -15x^2 + 15x + 2.
g(-2) =  18.
Step-by-step explanation:
f(g) = -5(3x^2 - 3x) + 2
= -15x^2 + 15x + 2.
g(-2) = 3(-2)^2 - 3(-2)
= 12 + 6
= 18.
 
        
             
        
        
        
Answer:
A =  15 a²b²c² square units
Step-by-step explanation:
Area of a rectangle = LW
                     A = (1.5abc)(10abc)
                     A =  15 a²b²c² square units
 
        
             
        
        
        
Well, let us solve this step by step.
We know that Michelle earns 349 plus 3% of the Purchase
price. Let us call the Purchase price as P, so that:
 
Earnings, E = 349 + 0.03 P
 
So if she earns 8,965 (E = 8,965) so we can find P:
 
8,965 = 349 + 0.03 P
0.03 P = 8,616
P = $287,200
 
        
             
        
        
        
Answer:
Neon: 0
Oxide:  -2
Copper:   2
Tin:  0
Step-by-step explanation:     To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20     therefore the charge is -20
 
        
                    
             
        
        
        
Answer: 15x + 6 
5x + 2x+3 = 7x+3 
6x+4 + 7x+3 = 13x + 7
13x+7 + 2x-1 = 15x+ 6
