Answer:
<em>You should buy the watch from Store A because it's cheaper</em>
Step-by-step explanation:
Store A sells a watch for $50 with a 5% discount.
Let's calculate the sale price. The 5% discount is
5/100*$50 = $2.50
The sale price is $50 - $2.50 = $47.50
Now for Store B. The price of the watch was $60 with a 20% discount.
Calculate 20% of $60:
20/100*$60 = $12
The sale price is $60 - $12 = $48
Thus, you should buy the watch from Store A because it's cheaper

Step-by-step explanation:
If the triangle is right then the square of the longest side (hypotenuse) will equal the sum of the squares of the other 2 sides.
longest side is x² + 1, then
(x² + 1)² =
+ 2x² + 1
The sum of the square of the other 2 sides
(x² - 1)² + (2x)²
=
- 2x² + 1 + 4x² =
+ 2x² + 1
Hence triangle is right
