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

Answer:
B is the answer for this question. :)
Step-by-step explanation:
(150 miles/week) x (1 gallon / 25 miles) x (3 $/gallon)
= (150 x 1 x 3) / (25) (miles-gallon-$ / week-miles-gallon)
= 18 $/week .
