the answer is m= -3
distribute the -2 then solve
m = -3
3-2*(9+2*m)-(m)=0
Step One :
(3 - 2 • (2m + 9)) - m = 0
Step Two: None.
Pulling them out like terms.
-5m - 15 = -5 • (m + 3)
Step Three:
-5 • (m + 3) = 0

Answer:
D(-5,3) and E(-5,1)
Step-by-step explanation:
|AB|² = (-1-5)² + (-6-2)²
|AB|² = 36 + 64
|AB|² = 100
|AB| = 10
AB/DE = 5
|DE| = 10/5 = 2
D(-5,3) and E(-5,1)
|DE|² = (-5+5)² + (3-1)²
|DE|² = 4
|DE| = 2
