Answer:
x < - 6 or x > 6
Step-by-step explanation:
Inequalities of the type | x | > a, always have solutions in the form
x < - a or x > a
given 4| x + 2 | > 16 ( divide both sides by 4 )
| x + 2 | > 4 ← in the above form, hence
x + 2 < - 4 or x + 2 > 4 ( subtract 2 from both sides of both inequalities )
x < - 6 or x > 6 ← solution
Answer:6/11
Step-by-step explanation:
Answer:
Either 12/5 or 2 2/5
Step-by-step explanation:
I times 16 and 9 together to make 144
and 3 and 20 together to make 60
144/60= 12/5 or 2 2/5
Answer:
2
Step-by-step explanation:

=2
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
