18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6  / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.
3^2 + x^2 = 14^2
9 + x^2 = 196
x^2 = 187
x = sqrt(187)
 
        
             
        
        
        
Answer:
5,5,7,*9,11,*12,16,23
Step-by-step explanation:
Since, the data has an even amount of numbers once, you put your numbers in order you place your pointer fingers from the 1st to last number & continue to move closer. There is an even amount of numbers so you would have to add the 2 numbers up & then divide them by 2.
9+11=20 divided by 2=10
 
        
             
        
        
        
To solve this equation by elimination, what you would do is multiply one of the equations by -1, or distribute -1 to each term in the equation, any of the 2 equations. Then align the equations and add them together. 
-(X + 3y = 3) 
-X - 3y = -3
-X - 3y = -3
X + 6y = 3 
__________
 3y = 0 
 y = 0/3 = 0. 
Now we can solve for x, by simply plugging the value of y into any of the 2 equations. 
X + 6y = 3 
X + 6(0) = 3 
X + 0 = 3 
X = 3. 
The solution to your system of equations would be (3,0). 
Check this by plugging in the point to the other equation and see if it is true.
X + 3y = 3
(3) + 3(0) = 3 
3 + 0 = 3
3 = 3.
Thus it is the solution.
