The cost for carpeting 20 square yards is $230.
Further explanation:
First of all, we will calculate the cost for one square yard then will find the final answer.
So,
Given
Total area = 28 square yards
Cost of carpeting 28 square yards = $322
Cost of carpeting one square yard = 322/28 = $11.5 per square yard
Now to find the cost of carpeting 20 square yards
Cost of 20 square yards = 20*11.5
= $230
The cost for carpeting 20 square yards is $230.

3 is the answer
mutiply and open bracket minus each other
Answer:
39$ and 50 cents
Step-by-step explanation:
because 35 plus 4.5= 39.5
Let the width be x, it length is 2x - 4
Area = length x width
x(2x - 4) = 170
2x^2 - 4x - 170 = 0
x^2 - 2x - 85 = 0
x = 10.27
Therefore, the width ≈ 10.27 ft and the length is 2(10.27) - 4 ≈ 16.54
Answer:
Step-by-step explanation:
Given quadratic equation is,
-32 = 2(x² + 10x)
-32 + 50 = 2(x² + 10x + 25)
18 = 2(x + 5)²
9 = (x + 5)²
± 3 = (x + 5)
x = -2 or x = -8
