for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)
for every x greater than zero, use the second line to determine the value
hope this helps and gives some insight what to do.
if there are open questions left, feel free to ask them in the comments
have a beautiful day

Hello!
If you add up the squares of the two legs, it will equal the square of the hypotenuse. As we already have the hypotenuse, we will subtract.
225-81=144
Now we find the square root.
√144=12
Therefore, the other leg is 12 cm long.
I hope this helps!

Answer:
d. 45
Step-by-step explanation:
You can check the offered answers. You will find that the difference from reversing the digits will only be 9 if the digits differ by 9/9 = 1.
The original number is 45.
__
<em>Check</em>
45 + 9 = 54 . . . with the digits reversed
3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
