Answer:
2
Step-by-step explanation:
the x and y are being multiplied by 2 e.g. 1 × 2 is 2 and 2 × 2 is 4 so the constant is 2 
 
        
                    
             
        
        
        
Let's find the slope for line t first.
We can use the given points 2,6 and 10,1 to find the slope using the slope formula.

1 - 6 / 10 - 2
-5/8
The slope is -5/8.
Because we know the slope of this line, we can find the slope of the next line instantly, as they are perpendicular. 
When a slope is perpendicular to another, it is equal to the negative reciprocal. 
Negative reciprocal of -5/8 = 8/5
<h3>The slope of line u is 8/5</h3>
 
        
             
        
        
        
The area of a square with sides of length s is
A=s^2, and we are told A=25 so
s^2=25
s=√25
s=5m
        
                    
             
        
        
        
Hello, 
x= the number
3x= three times the number
seven decreased by three times a number is forty, then:
7-3x=40
-3x=33
x=-11
Answer: the number is -11
