Answer:
The special right triangle that has a hypotenuse of 13 units is the right triangle that has legs of length 5 units and 12 units.
The answer is 13 and 18
<span>Two numbers have the product of 234: x * y = 234
</span>Two numbers have the sum of 31: x + y = 31
This is the system of equations:
x * y = 234
x + y = 31
_______
x * y = 234
y = 31 - x
_______
x(31 - x) = 234
31x - x² = 234 (-1)
-31x + x² = -234
x² - 31x = -234
x² - 31x + 234 = 0
According to the quadratic equation formula:

When: x1 = 18, y1 = 31 - 18 = 13
When: x2 = 13, y1 = 31 - 13 = 18
