Answer:
n = -4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
combine like tmers:
6n + 9 = -3n - 27
add 3n to both sides:
9n + 9 = -27
subtract 9 from both sides:
9n = -36
divide by 9:
n = -4
Answer:
v = ± 
Step-by-step explanation:
Given
E = 
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ±
If x+4>13 then it would be x>9
6! If you do 60 times 6 you get 360.
