Answer:
16x+2
Step-by-step explanation:
Perimeter- Length+width x2
(6x+4+2x-3)2
(8x+1)2
16x+2
 
        
             
        
        
        
Ans
184 sq meter
Step-by-step explanation:
Area of the cuboid box = (2*FA)+(2*SA)+(2*TA)
Where FA= Front face area
SA= Side face area
TA= top face are
Here FA= length * breadth = 10*6=60 sq meter 
SA= 10*2= 20 sq meter
TA= 6*2= 12 sq meter
So area of box= 2*60+2*20+2*12= 184 sq meter
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Rewrite the system of equations as:

Subtract the second equation from the first to isolate  :
:

Plug in  into any of the equations above and solve for
 into any of the equations above and solve for  :
:

Verify that the solution pair  works
 works 
Therefore, the solution to this system of equations is:

 
        
             
        
        
        
The correct answer is B) y + 9 = 2(x - 1)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form. 
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 9 = 2(x - 1)
 
        
             
        
        
        
(a) 

 = 400
(b) 


(c) Only the positive solution makes sense because you cannot have a negative side length.
(d) Since one side of the painting is 20 inches, all four sides together will be 20*4 = 80 inches
