Answer:
The answer to your question is 11.4 units
Step-by-step explanation:
Data
A (-3, -1)
B ( 0, 3)
C ( 1, 2)
Perimeter = ?
Formula
d = 
Process
1.- Find the length between the points
 dAB = 
dAB = 
dAB = 
dAB = 
dAB = 5 
dBC= 
dBC = 
dBC = 
dBC = 
dAC = 
dAC = 
dAC = 
dAC = 
dAC = 5
2.- Perimeter
P = AB + BC + AC
P = 5 +  + 5
 + 5
P = 10 + 
P = 10 + 1.42
P = 11.4
 
 
        
             
        
        
        
Answer:
The answer is 7/3 or 2 1/3
Step-by-step explanation:
1) You change the ÷ into x  (so it will be 7/9 x 1/3)
2) You flip the 1/3 so it will be 3 ( 7/9 x 3)
3) There you have it the answer is 7/3
 
        
             
        
        
        
Answer:
45
Step-by-step explanation:
We make a proportion and solve it:

28 x = 20x+360
8x=360
x=45
 
        
             
        
        
        
Its basically telling you to multiply 3x+2 × 7x+6
21x^2+18x+14x+12
21x^2+32x+12
