Answer:
=6r−18
Step-by-step explanation:
Distribute:
=2r+−6+(4)(r)+(4)(−3)
=2r+−6+4r+−12
Combine Like Terms:
=2r+−6+4r+−12
=(2r+4r)+(−6+−12)
=6r+−18
 
        
                    
             
        
        
        
Answer:
62 cm
Step-by-step explanation:
Given the expressions for width (3x + 1) and length (5x - 2) as well as the formula for the perimeter of a rectangle: 2(5x - 2) + 2(3x +10), we can first solve for the simplified expression of 'x' and then substitute the given value of x = 4cm to find the total distance: 
Distribute: 2(5x - 2) + 2(3x +1) = 10x - 4 + 6x + 2 
Combine like terms:  16x - 2
Plug in '4' for 'x':  16(4) - 2 = 64 -2  = 62 cm 
 
        
             
        
        
        
Beginning inventory
10×25=$250
Purchase
20×30=$600
So
Beginning inventory 250
Add purchase 600
Less ending inventory 500
Material used. 350
The answer is 350
        
             
        
        
        
Hey :)
x= -12
Use the distributive property to multiply −4 by 2x+13
−8x−52=3x+80
Subtract 3x from both sides
−8x−52−3x=80
Combine −8x and −3x to get −11x
−11x−52=80
Add 52 to both sides
−11x=80+52
Add 80 and 52 to get 132
−11x=132
Divide both sides by −11
x= 132/-11
	
Divide 132 by −11 to get −12
x=−12
Hope this helps :)
        
             
        
        
        
Given:
Consider the below figure attached with this question.
To find:
The solution to this linear system.
Solution:
From the below graph it is clear that both lines intersect each other at point (2,3).
Here,
x-coordinate = 2
y-coordinate = 3
Therefore, the solution to the given system is (2,3).
Hence, the required answer for first blank is 2 and for second blank is 3.
