Denote by m for marinara and by a for alfredo and recall the following law:

Therefore

The correct answer is the last one.
Answer:
a) Length = 
b) Width = 27 units
Step-by-step explanation:
We are given the following in the question:
Area of rectangle, A =

Width of rectangle, w =

a) Length of the rectangle.
Area of rectangle is given by:

where l is the length of rectangle.
Putting values, we get,

b) Width of rectangle
Length of rectangle = 80

Thus, width of rectangle is

Thus, the width of rectangle is 27 units.
I believe the first one would be non linear
2n^2-20=0
2n^2=20
n^2=20÷2
n^2=10
n=radical 10
First, you will have to convert all of these numbers to decimals.
2/3=0.6 repeating
25%=0.25
3/5=0.6
0.40 is already in the decimal form
Then, you order them.
25%, 0.40, 3/5, 2/3 (because the 6 is repeating. So basically 0.60 is smaller than 0.66 in case you are wondering)
