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.
Since 2 cases = $48
÷ 48 by 2 to get the cost of one case of paper
48÷2=$24 per case
and each case has 12 pack of paper
so $24 for 12 packs of paper
180÷12=15, which gives you the number of case you need
15 cases × $24= $360 for 180 packs
20000000+ 4000000+ 80000+ 4000+ 100+ 60+ 3
I have no clue. This is because I honestly want more points. So yea thank you for understanding.
It is about $5.89 for one pair of work gloves. You divide 494.92 by 84 (7 dozen) and that is your unit price.
