The answer is 15x+7! :)
14x+x=15x and there is no other numbers that 7 can be added or subtracted by.
The equation for the area of a circle is: A = πr^2.
A: Area
π: pi
r: radius
To find exact area (we leave pi in the answer):
- Find the radius of the circle.
The diameter 5ft.
The radius is half the diameter so r = 2.5 ft
-plug in 2.5 for r in the area equation
A = π(2.5)^2
2.5^2 is 6.25
A = π6.25
A = 6.25π
There you go! The exact area of the circle is 6.25π ft^2
To approximate the area instead of using π in the equation we use (3.14)
So,
A = (3.14)(2.5)^2
A = (3.14)*6.25
Approximated Area = 19.625 ft^2
Answer:
range: (-infinity,+infinity)
C more than one because have you ever seen a formula that has one variable? For instance, x is not a literal equation. A=bh is a basic literal equation there is no cap on a number of variables that can be in a literal equation as long as it is more than one.
Since it costs four time more all u have to do is to divide 140 by 4 and the novel costs $35
