Given:
The three equations for the three numbers are



To find:
The Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
Substituting x=4 and and y=1 in the given equations, we get



In the same way find b and c.


The third number is



The required Pythagorean triple is 8, 15, and 17.
Therefore, the correct option is C.
 
        
             
        
        
        
[(8+10)/3]+3.(7-3)=(18/3)+3.(4)=6+12=18

Answer:
11. AW║BY
12. DX║YZ
13. AW║YZ
14. AW║DZ
Step-by-step explanation:
11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.
12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.
13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.
14. Lines perpendicular to the same line are parallel.
 
        
             
        
        
        
Answer: 
5x + (- 1)
Step-by-step explanation:
So the terms are 2x, -5, 3x, and +4. 
2x and 3x have x in common so they can be combined to create 5x. 
-5 and +4 don't have variables, so they are also common and can be combined to make -1.
