Parallelogram have 4 sides.
Use the distributive property. 2 multiply the last and negative 4 in the parentheses.
2l + 2(l - 4) = 72 m
Combine Like terms
2l + 2l - 8 = 72 m
4l - 8 = 72 m
Get l all by itself by adding 8 to both sides
4l - 8 = 72 m
+8. +8
Divide both sides by 4
4l = 80
4. 4
l= 20
The width of the parallelogram is four meters less than its length.
4 sides
2 length = 20
2 width = 16
I got 16 by subtracting 4 from 20
Comment if you need any other help :)

2. ![3x^{2} -19x-14](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-19x-14)
Step-by-step explanation:
1. Just subtract them. (To subtract easier, ignore the variables and subtract regularly. When you're done go back and put the variables back in)
2. Foil
