Part of the roof of a factory is developed to mechanical support and part to green space. THe area of the roof R of a larger bui

lding can be modeled by the polynomial 2x2-251x+80000 and the area of M roof that is devoted to mechanical support can be modeled by the polynomial x2+2241x+31250. The rest of the area is a rectangular green space. Given the area of G of the green space is 123,750 square feet, write and solve the quadratic equations to find the dimensions of the green space.

Answer:

(x + 125), (x - 600)

Step-by-step explanation:

The objective is to write and solve the quadratic equations to find the dimensions of the green space.  

The given information is

The area of the roof R of a large building is

2x^2 -251x+ 80,000

The area devoted to Mechanical support is  

x^2 + 224x+31250

The area of the green space is 123,750 square feet.

James is running on a trail that is 5/4 of a mile long. So far he has run 2/3 of the trail. How many miles has he run so far?
aalyn [17]
Step 1) You would need to convert your 2 fractions into equivalent numbers. In this case, the closet gcf (greatest common factor) is 12. So, 5/4 would convert to 15/12 and  2/3 converts to 8/12.

Step 2) You know have your decimals that are equivalent. All you have left now is to subtract. Take 15/12 and subtract 8/12 from it. You would now get 7/12 of a mile that is still needed to run. 

Step 3) Usually, you would simplify your new fraction. In this case, our fraction doesn't simplify. It will stay 7/12 of a mile. For example, If our number had ended up being 4/12, then we would simplify it to 1/3 of a mile. Because, 4 divided by 4 is 1 and 12 divided by 4 is 3. You can't simplify your answer anymore.

Hope this helped!
