Answer:
For the first statement, we need to prove that for all real numbers x and y, √x+y = √x + √y is true.
To prove this statement is true, we can square both sides of the equation: (√x + √y)^2 = x + y + 2√xy x + y + 2√xy = x + y + 2√xy Therefore, the statement is true for all real numbers x and y.
For the second statement, we need to determine if all occurrences of the letter t in the phrase "Good Luck" are lowercase.
This statement is false. There is one occurrence of the letter t that is uppercase in the phrase "Good Luck", which is the "T" in "Good". Therefore, the statement is false.
