Answer:
6 and 10
Step-by-step explanation:
xy=60
2(x+y)=32
x+y=16
y=16-x
Substitute y into area equation
x(16-x)=60
16x-x^2=60
x^2-16x+60=0
(x-10)(x-6)=0
x=10, 6
y=6, 10

Answer:

Where "h" is the height of the building.
Step-by-step explanation:
For this exercise it is important to read and analize carefully the information provided.
According to the data given in the exercise, the height of each floor the arquitect is designing is 12 feet.
You want to know the number of floors of 12 feet tall that building can have for a given building height.
Then, you can let "h" represents the height of the building. This will be the variable in the expression.
In order to find the number of those floors that the building can have for "h", you need divide this height by the height of each floor.
Therefore, you can determine that the expression asked in the exercise is the following:

Where "h" is the height of the building.
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
