Answer:
√85
Step-by-step explanation:
The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...
... d = √((x2-x1)^2 +(y2-y1)^2)
For your points (-1, -4) and (-8, 2), the distance is ...
... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)
... d = √85
The distance between the two points is √85.

Answer:
p = - 5, p = - 1
Step-by-step explanation:
Given
-
= 
Multiply through by the LCM of (p - 5)(p + 3)
3p(p + 3) - 2(p - 5) = p(p - 5) ← distribute parenthesis
3p² + 9p - 2p + 10 = p² - 5p
3p² + 7p + 10 = p² - 5p ( subtract p² - 5p from both sides )
2p² + 12p + 10 = 0 ← divide through by 2
p² + 6p + 5 = 0 ← in standard form
(p + 1)(p + 5) = 0 ← in factored form
Equate each factor to zero and solve for p
p + 1 = 0 ⇒ p = - 1
p + 5 = 0 ⇒ p = - 5
D -9 because it has a -3 and its going to be the same - sign
