Answer:

this is the formula u can use it on any Pythagoras theorm problem
Answer:
2/1 or 400/200
Step-by-step explanation:
-2 sqrt (20) -sqrt(125)
-2 sqrt(4*5) - sqrt(25*5)
-2 sqrt(4)sqrt(5) -sqrt(25)sqrt(5)
-2 *2*sqrt(5) -5sqrt(5)
-4sqrt(5) -5sqrt(5)
-8sqrt(5)
Following the example given where "square, then subtract 5" refers to squaring the variable x and then subtracting 5 from it.
f(x) = x² - 5
The "rule" we must then express in function notation is "subtract 6, then square". The rule appears to suggest that the number 6 is being subtracted from the variable x. Then the entire expression is squared, resulting in the following function:
f(x) = (x - 6)²
