1 gallon = 16.8 miles
265 gallons = 16.8 x 265 = 4452 miles
Answer: 4452 miles
Example 1 Perform the indicated operation for each of the following.
<span>(a) </span>Add to
<span>(b) </span>Subtract
Solution
(a) Add to .
The first thing that we should do is actually write down the operation that we are being asked to do.
In this case the parenthesis are not required since we are adding the two polynomials. They are there simply to make clear the operation that we are performing. To add two polynomials all that we do is combine like terms. This means that for each term with the same exponent we will add or subtract the coefficient of that term.
In this case this is,
[Return to Problems]
(b) Subtract from .
Again, let’s write down the operation we are doing here. We will also need to be very careful with the order that we write things down in. Here is the operation

Answer on Question #47534 – Math – Geometry
How to prove the volume formula of con is 1/3×π×r^2×h;without using
integration?
Solution.
Suppose we take a slice of the pyramid with the cone inside, from some way up
the pyramid. This will look like a square with a circle fitting inside. Radius of the
cone at this point, will be x.
The area of the circle is
The area of the square is × =
The ratio of the circle to the square is
.
The same is true for every slice we take: the area of the circle is
of the area
of the square.
So, the volume of the cone will be
the volume of the pyramid.
The pyramid's volume is
.
So the cone's volume is
