3(2x+1) If you multiply this out, you will get 6x+3. 
A = 4(6x + 3)
A = 4(6x) + 4(3)
A = 24x + 12
The answer is 24x+12.
        
                    
             
        
        
        
Answer:
x = √21.
Step-by-step explanation:
Triangles ADB and BCD are similar.
So their corresponding sides are in the same ratio:
x / 7 = 3 / x
x^2 = 21
x = √21.

Answer:
y = -1x + 2
Step-by-step explanation:
- y=mx+b
- going down to the right negative slope
- rise over run so 1/1 makes the slope 1
- negative 1 for the slope
- b is the y-intercept and the line lands on the point (0,2)
