<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!

It is a because it can’t be B and it can’t be C and it can’t be D so my answer is a
16500 Rounded to the nearest ten thousand is 20,000
First convert the percent to decimal form by moving the decimal point two places to the left which equals 0.08. Then multiply that by the sale price of the TV pre tax ($640.00) which equals 51.2. Finally add 51.2 to the sale price of the TV which equals $691.20.
