Answer:

$\Huge \boxed{(x+1)^3}$

Step-by-step explanation:

x³ + 3x² + 3x + 1

Apply cube of sum rule :

⇒ a³ + 3a²b + 3ab² + b³ = (a + b)³

(x)³ + 3(x)²(1) + 3(x)(1)² + (1)³

⇒ a = x

⇒ b = 1

Point A is at (3, -8) and point B is at (7, 3). What is the midpoint of line segment AB?

allochka39001 [22]

Answer:

$(5, -5/2)$

Step-by-step explanation:

The midpoint of any line segment is the average of the x- and y-values of the two endpoints.

Therefore, the midpoint of $AB$ is $((3+7)/2, (-8+3)/2)=(10/2, -5/2)=(5, -5/2)$ .

So, the answer is $\boxed{(5, -5/2)}$ and we're done!
