A line parallel to x = 8 will be of the form:

where k is a constant.
It passes through (-3,-2)
Thus, 

 
 
        
        
        
using the pythagorean theorem
a^2+b^2 = c^2   where c is the hypotenuse
9^2 +12^2 = x^2
81 + 144 = x^2
225 = x^2
taking the square root of each side
sqrt(225) = x
15 =x
x = 15 inches
 
        
                    
             
        
        
        
Answer:
x = 13ft
Step-by-step explanation:
The isosceles triangle is a polygon with three sides, two being equal and the other unequal.
The angles P and N will also be equal  and the M other different.
PM ≅ MN
∠P ≅ ∠N
PN = 2x
because the line starting at M divides the triangle into two sections
26 = 2x
2x = 26
x = 26 /2
x = 13ft
 
        
             
        
        
        
Answer:
K = 7 or 1
Step-by-step explanation:
(7-7)(7-1)=0
(1-7)(1-1)=0
 
        
             
        
        
        
The discount would be - $1.09 
So the final price would be $9.83
