Answer:
168/(x² +7x)
Step-by-step explanation:
The height of each window is 14/(x+7), and the width of each window is 12/x. The area of each window is the product of its height ans width:
area = (14/(x+7))(12/x) = 168/(x(x +7))
area = 168/(x² +7x)
_____
<em>Comment on the problem</em>
There is not enough information given to determine suitable values for x. If x is 42, each window is a square 3 3/7 inches on a side.
Step-by-step explanation:
15 + 10 = 25 people
15 are girls and 10 are boys and that makes 15/10 ratio.
15/10 divided by 5 each is 15/5=3 and 10/5=2 which gets you a simplified fraction of
3/2
Hope this helped!
Answer:
(4,1)
Step-by-step explanation:
The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).
To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.
To find the y-coordinate, input the x=4 and solve for y.
The vertex is (4,1).
Answer:
Yes
Step-by-step explanation:
This is called Box and Whiskers or box plot.
The box in the middle contains 50% of data and the right end of the box is 75th percentile, you are correct.
25% of data is distributed to the left and 25% of data to the right of the box that is in the middle.

Answer:
5∛(x²)
Step-by-step explanation:
The denominator of a rational power is the index of the radical when the expression is written in radical form.
