AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1

What is the distance between the two points in simplest radical form? P(2,8) and B(1,3)

erica [24]

Answer:

$\sqrt{26}$

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = P(2, 8) and (x₂, y₂ ) = B(1, 3)

$d_{PB}$ = $\sqrt{(1-2)^2+(3-8)^2}$

= $\sqrt{(-1)^2+(-5)^2}$ = $\sqrt{1+25}$ = $\sqrt{26}$
