Answer:
Third option, 
Step-by-step explanation:
By observation, we can infer that
 .
.
Subtract 8 from both sides:


Subtract 4x from both sides:


Divide both sides by -1:


 
        
                    
             
        
        
        
The answer would be m^2+3m+2=0 because the first “part” of the equation (x^2-5) is equal to m; in the equation it’s squared so it can be replaced by m^2. next, 3m is the same as 3(x^2+5) which is what you have when you see 3x^2+15. finally, you have to bring the -2 over from the other side so you have positive 2. hope this helps!
        
             
        
        
        
-22 belongs to the set of Integers, rational numbers
 
        
             
        
        
        
Length: w+4
Width:w
Perimeter:44
Area: L times w
P=44
44=2(w)+2(w+4)
44=2w+2w+8
44=4w+8
36=4w
w=9
L=w+4
L=9+4
L=13
Area should equal 117 cm squared
