Given:
The volume of the rectangular prism is
Two dimensions are (x+1) and (x+3).
To find:
The missing dimension.
Solution:
We know that, volume of a rectangular prism is
It means, volume of a rectangular prism is the product of all dimensions.
We have,
Splitting the middle terms, we get
Splitting the middle term, we get
So, the three dimensions of the rectangular prism are (x+1), (x+3) and (4x-11).
Therefore, the missing dimension is (4x-11).
Answer:
A.) an algebraic expression
Step-by-step explanation:
Note that there are only integers (whole numbers) and the usage of algebraic operations. Also note that there is no "equal" sign (which would make it an equation), making the problem a expression.
