and 
Step-by-step explanation:
The expression is 
and 
Using substitution method we can solve the expression.
Let us substitute 
in
Expanding and simplifying the expression, we get,
Let us use the quadratic equation formula to solve this equation,
Thus, 
and 
Substituting y-values in the equation , we get the value of x.
For ⇒ 
For ⇒

Answer:
C.) 5, 12, 13
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).
a² + b² = c²
We can test each set of numbers to see which one fits.
A.) 8² + 12² = 16²
64 + 144 = 256
208 ≠ 256
B.) 6² + 7² = 8²
36 + 49 = 64
85 ≠ 64
C.) 5² + 12² = 13²
25 + 144 = 169
169 = 169
The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.
D.) 16² + 32² = 36²
256 + 1024 = 1296
1280 ≠ 1296
