<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!

Given expression is
And we have to find the slope of the tangent line at the point (1,5), and for that, first we find the derivative of the given expression, which is
And the derivative is the slope. And to find the slope at point (1,5), we put 1 for x in the expression of derivative, that is
Hence, the slope of the tangent line to the parabola at the point (1, 5) is 4.
Answer:
648
Step-by-step explanation:
360 miles / 5 hours = 72 miles per hour
72 mph × 9 hours = 648 miles
Answer:
x<-3
Step-by-step explanation:
Generally four, but polynomials may have repeated roots. “Could” contain four different binomial, but they just happen to be the same.
