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

<h3>
Answer: C) x = 13</h3>
====================================================
Work Shown:
We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.
Use the pythagorean theorem to find x.
a^2 + b^2 = c^2
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
x^2 = 169
x = sqrt(169) .... apply the square root to both sides
x = 13
Answer:
A is the least number of packs
Step-by-step explanation:
The answer is the second choice
Answer:
The missing side is 8 ft long
Step-by-step explanation:
According to Pythagoras theorem <em> "It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"</em>
mathematically it is stated as

Given that
c, hypotenuse= 17 ft
a = 15 ft
b= ?
Applying the Pythagoras theorem formula by inserting our given parameters and solving for b we have

Making b subject of formula we have

Square root both sides we have

Hence the missing side is 8 ft long
