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.
Answer:
Percentage change=140%
Step-by-step explanation:
The expression for the percentage change is as follows;
C={(F-I)/I}×100
where;
F=final quantity
I=initial quantity
C=percentage change
In our case;
C=unknown
F=24 gallons
I=10 gallons
replacing;
percentage change={(24-10)/10}×100
percentage change=(14/10)×100
percentage change=140%
