X=2 
you multiply by 8 on both sides. so that your equation now looks like x-2=0 
then you will add by 2 on both sides. 
x=2

Answer:
sqrt(10) *x 
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + (3x)^2 = hypotenuse ^2
x^2 + 9x^2 = hypotenuse ^2
10x^2 = hypotenuse  ^2
Take the square root of each side
sqrt( 10x^2) =  sqrt(hypotenuse  ^2)
sqrt(10) * x = hypotenuse
 
        
                    
             
        
        
        
Answer:
A) 29 
Step-by-step explanation:
DG = GJ
GJ = DG = 4x + 17
DJ = DG + GJ
11x + 25 = 4x + 17 + 4x + 17
11x + 25 = 4x + 4x + 17 + 17    {Combine like terms}
11x + 25 = 8x + 34
Subtract 25 from both sides
11x = 8x + 34 - 25
11x = 8x + 9
Subtract 8x from both sides
11x - 8x = 9
3x = 9
Divide both sides by 3
x = 9/3
x = 3
DG =  4x + 17 
      = 4*3 + 17
     = 12 + 17
DG = 29
