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 :)
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
30.
3/4 is equal to 75%, so take 75% of 40 by multiplying .75 by 40 to get 30

Answer:
11.)
We can let the scores we don't know by x, and we know that tokay had 14 more points than Lodi. This can be shown as the following:
x + (x+14) = 162
2x+14=162
162-14= 148
148/2 = 74
Therefore Lodi scored 74 points.
12.)
We can substitute the prices we don't know by x and have the following:
4x+x=6.50
5x=6.50
6.50/5= 1.3
4x1.3= 5.2
Therefore the sandwich cost $5.20 and the drink costs $1.30
