Answer:
x > 1 or x < 7
Step-by-step explanation:
| x - 4 | < 3
± ( x - 4 ) < 3
There are two possible cases
( x - 4 ) < 3 or - ( x - 4 ) < 3
x - 4 < 3 or - x + 4 < 3
x < 3 + 4 or 4 - 3 < x
x < 7 or 1 < x
x > 1 or x < 7
Therefore option 4 is correct.
Answer:
a^2 + b^2 - c^2 + 2ab
Step-by-step explanation:
(a + b - c)(a + b + c)
1. expand
(a^2 + ab + ac + ba + b^2 + bc - ca - cb - c^2)
2. rearrange,
(a^2 + b^2 - c^2 + ab + ba + ac - ca + bc - bc)
3. add and subtract
(a^2 + b^2 - c^2 + 2ab)
Answer:
x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3
Step-by-step explanation:
Subtract 15 from both sides
8x=-15
Divide 8 on both sides
Now you get your answer
x=-15/8 or -1 7/15
OR
Combine like terms
9x+15=0
Subtract 15 from both sides
9x=-15
Divide 9 from both sides
x=-15/9
Simplify
x=-5/3 or -1 2/3
