Answer:
- 8
Step-by-step explanation:
Answer: x = 9, 5
<u>Step-by-step explanation:</u>
4 | x - 7 | + 2 | x - 7 | = 12
6 | x - 7 | = 12 <em>added like terms</em>
| x - 7 | = 2 <em>divided both sides by 6</em>
x - 7 = 2 or x - 7 = -2 <em>removed absolute value sign</em>
x = 9 or x = 5 <em>added 7 to both sides of both equations</em>
I believe the answer is 1. One is the only number that can go into both 8 and 9.
The answer is:
D. Ac = {xΙx ∈ U and is an even positive integer}
