Answer:
A
Step-by-step explanation:
For lines to be parallel, their slopes need to be the same.
For lines to be perpendicular, the product of their slopes needs to be -1.
None of these conditions are met since the slopes are 2 and 4 respectively.
Sooo.... The answer must be A! :)

Answer:
x = -5/21
Step-by-step explanation:
Step 1: Write equation
2(12x - 1) = (21x - 49)/7
Step 2: Solve for <em>x</em>
- Multiply both sides by 7: 14(12x - 1) = 21x - 49
- Distribute 14: 168x - 14 = 21x - 49
- Subtract 21x on both sides: 147x - 14 = -49
- Add 14 to both sides: 147x = -35
- Divide both sides by 147: x = -5/21
Here are some factors of 20!
1x20=20
2x10=20
4x5=20
5x4=20
Therefore there are 4 factors of 20.
