<em>x³ + x²y - xy² - y³</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>(x − y)(x² + 2xy + y²) =</em>
<em>= x(x² + 2xy + y²) - y(x² + 2xy + y²)</em>
<em>= x³ + 2x²y + xy² - x²y - 2xy² - y³</em>
<em>= x³ + x²y - xy² - y³</em>
<em>Good luck !</em>
Hello!
The answer to this is B!
Answer/Step-by-step explanation:
Let's use Pythagorean theorem:
Formula : a² + b² = c²
Note that:
a is the long leg of the triangle
b is the short leg of the triangle
c is the hypotenuse
Side lengths Given are; 3 inches, 4 inches, 5 inches of a right triangle.
Hence,
a = 4 inches
b = 3 inches
c = 5 inches
Thus,
4² + 3² = 5²
16 + 9 = 25
25 = 25 [True]

Hello!
To find the mean you add all the numbers and divide the sum by the amount of numbers added
14 + 19 + 18 + 12 + 22 + 15 + 16 + 16 + 14 + 14 + 21 + 20 = 201
Divide the sum by the amount of numbers added
201 / 12 = 16.75
The answer is C) 16.75
Hope this helps!
