Answer:
1. n is 1 or -1
2. x is 6 or -6
Step-by-step explanation:
1. |n| -4 = -3
|n| = -3 + 4
|n| = 1
so n = 1 or - 1
2) -3|x| = -18
divide both sides by -3
|x| = -18/-3
|x| = 6
so x = -6 or 6

Step-by-step explanation:
Answer:
-3a² - ab - 7ac - 2b² + 6bc + 4c²
Step-by-step explanation:
Step 1: Distribute
3a² + 3ab + 3ac - 2ab + 2b² -2bc
Step 2: Combine like terms
3a² + ab + 3ac + 2b² - 2bc
Step 3: Distribute again
-4ac + 4bc + 4c² - (3a² +ab + 3ac + 2b² -2bc)
Step 4: Combine like terms again
-3a² - ab - 7ac - 2b² + 6bc + 4c²
And you have your final answer.
Answer:
40 meters
Step-by-step explanation:
