If we observe closely the given, we can note that the
terms given are perfect cubes. That is,
<span> x^3 is
cube of x and</span>
<span> 343 is
cube of 7</span>
Hence, the expression is the sum of two cubes. For the
sum of cubes, we follow the following rule for the factoring:
<span> a^3 + b^3 = (a +
b)(a^2 – ab + b^2)</span>
Applying the rule to the given, the factors would be:
<span> X^3 + 373 = (x +
7)(x^2 – 7x + 49)</span>
Answer: 2x^9 Hope this helps!

The mean price and median price are close together.
Answer: Option 2
<u>Explanation:</u>
The shape of the graph which is shown in the picture is symmetric. Since it is symmetrical in shape, most of the data is clustered together around the center. This center is the median. The mean will be close to the median, since most of the data values are close to this.
The graph shows that the prices of the beverages are some where near and close to each other. The prices are not at extreme ends and this makes the shape of the graph symmetrical. Had there been any kind of extreme ends, then the shape of the graph would not have been the same.
Then
which is a disk of radius 1, hence with area
