Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box
----------------------------------------------------
----------------------------------------------------
The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x
Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter).
The height of the box is x inches due to this portion being folded up.
Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x
Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).

please be more specific
Answer: a<b
Step-by-step explanation:
Given statement: "a number <em>a</em> is always less than another number <em>b."</em>
<em />
We use "<" or ">" sign to show less than or more than comparison in a mathematical statement.
If <em>a</em> is less than <em>b </em>then it can represented as
<em>a < b</em>
The expressions expresses the relationship between <em>a</em> and <em>b</em> would be:
<em>a < b</em>
