<h3>Answer :</h3>
The factor of (x + y)³- (x³ + y³) is <u>3xy</u>
<h3>Step By Step Solution :</h3>
→ (x + y)³- (x³ + y³)
→ (x + y) - (x + y)(x² - xy + y²) [Using identity a³ + b³ = (a + b)(a²- ab+ b²)]
→ (x + y)(x² + y² + 2xy - x² + xy - y²)[Using identity, (a + b)² = (a² + b²+ 2ab)]
→ (x + y) (3xy)
→ 3xy
∴ Option d. 3xy is correct!

Answer:
No
Step-by-step explanation:
This table does not represent a function. The domain(x) can have only one range(y) in order for a set of data to represent a function. However, the domain value 2 has the range of both 1 and 4. Therefore, the table does not represent a function.
Answer:
k = 24
y = 24x
Step-by-step explanation:
72/3 = 24
y = 24x
72 = 24(3)
72 = 72
Hope this helps!
A regular polygon has the same amount of sides and angles
Ok. So what I did was I chose a number that would be easy to manipulate The number I chose was 10, I then multiplied it by 4 to get 40, then subtracted 3 to get 37 - that was the first part of the question. The second part wanted me to take the same number, multiply it by 3 and then add 7. So 10 multiplied by 3 is of course 30 and then you just add 7 to get 37. Hey look! Its a match! I hope this helps.
P.S. - If you think I did a good job I would love it if you went to my YouTube channel to see if I can help you more there. Here is the link: https://www.youtube.com/channel/UCG0zQcSsxZ2mu-OnZRdI2-Q . I hope to see you there!
