Martins sisters age is 14 I got this My work (could be wrong)
Its pretty simple if they said Their sum of their ages is <u>22</u> all you have to do is 22-6= 14.  
Hope this helps If you have any questions ask me in the comments :D
 
        
                    
             
        
        
        
It's 3.74 rounded up to 4  the reason why it is that answer is because the formula to a triangle's Hypotenuse is A squared + B squared =  C squared 
        
             
        
        
        
Answer:
A. x=13
Step-by-step explanation:

 
        
             
        
        
        
F(5) = -1 would be the correct answer.
        
                    
             
        
        
        
The slope of the line passes through the points (-5,6) and (-3,2) is 2.
<h3>What is a slope?</h3>
Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise to the run.
Given that the line that passes through the points (-5,6) and (-3,2). 
The slope of the line is calculated by the formula,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 6 - 2) / ( -3 + 5)
Slope = 4 / 2
Slope = 2
Therefore, the slope of the line passes through the points (-5,6) and (-3,2) is 2.
