Answer:
2/3
Step-by-step explanation:
I assume the 2 after the j is a square. So, we bring the 21 to the other side by subtracting it from both sides, getting 144j^2=64. Now we divide to get 64/144 = j^2. Make sure NOT to simplify it, it's perfect right now. The square root of that is 
, or 8/12, which we can now simplify to 2/3. Hope this helps!
<span>The opposite sides can be proven parallel to each other if the lines would not intersect each other if the lines were much longer. It should also have the same straight horizontal measurement of distance in between the space. Measurement of parallel lines in a parallelogram can be determined using the slope formula.</span>

Answer:
y=6
Step-by-step explanation:
4(2y-3)-2y=24
Distribute
8y -12 -2y = 24
Combine like terms
6y -12 = 24
Add 12 to each side
6y-12+12 =24+12
6y = 36
6y/6 =36/6
y = 6
