Answer:

19.8 Units

Step-by-step explanation:

AB = √(3+2)² + (3-0)² = √34 = 5.8

AC = √(-2-(-4))² + (3+3)² = √40 = 6.3

BC = √(3-(-4))² + (0-(-3))² = √58 = 7.6

perimeter = 5.8 + 6.3 + 7.6 = 19.7

What is the value of n in the relationship 8n+9=-n+5

vitfil [10]

Subtract 5 from both sides.

$8n + 4 = -n$

Subtract 8n from both sides.

$4 = -9n$

Divide both sides by -9 to solve for n.

$- \frac{4}{9} = n$

The value of n is -4/9.
