I would go with A. 0.06 but I am not 100% sure.
Answer: 8 feet, D
Step-by-step explanation:
To solve this, use the Pythagorean Theorem. It states:

where A and B are the sides of a triangle and C is the triangle's hypotenuse.
The 17 foot ladder in this situation is your hypotenuse, and you have one side of the triangle: 15.

15 squared = 225
17 squared = 289
solving for b squared, we get 
taking the square root of 64, you get 8 feet, the distance between the house and the base of the ladder.
(Y+22) + 3 = Y + 22 + 3 = Y + 25
Answer:
All real numbers except 0
Step-by-step explanation:
0 is the only number that's going to make it undefined (btw if you mark brainliest it would be appreciated :) ).
