Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14) 
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
 
        
             
        
        
        
Answer:
A = 2.1 ft^2
Step-by-step explanation:
The area of a triangle is 
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 2.8)(1.5)
A = 2.1 ft^2
