Gerald purchases a rectangle plot of land The length of the plot is 20 feet more than the width. The cost of the land was $12 pe
denpristay [2]

Answer:

12x^{2}+272x+320=10560

Step-by-step explanation:

Start by setting the width = x.

Length is equal to x+20.

We know the cost of the land was $12 per square foot (area) and the cost of the fence around the perimeter is equal to $8 per foot.  This gives us two equations we need to work with.

$12(x*(x+20)) + $8((2*x)+(2*(x+20))) = 10560.  It looks a little difficult to read but as we distribute the cost throughout the equations, we see it start to take shape.

12(x^2+20x) + 8(2x+2x+40) = 10560

12x^2+240x+16x+16x+320 = 10560

12x^2+272x+320=10560

The roots of our equation here are x=20, and x = -128/3

Since we know that area is not negative, our answer is x=20.

Check the work: 12(20)^2 + 272(20) +320 = 10560

Let x be the number of song points.
Let y be the number of videos points.

We have the first expression:
5x + 7y = 295

We have the second expression:
10x + 3y=150

Solve for y and x:
x = (295 -7y)/5
10 ((295-7y)/5) + 3y  = 150
590 - 14y + 3y =150
590 - 150 = 14y -3y
y=40 points

solving for x:
x = (295-7*40)/5
x=3 points/song

If she buy, all songs for 333 points
number of songs = 333 / 3
number of songs = 111

The answer is 111.
