What shape best describes the cross section cut parallel to the base of a right rectangular prism?
2 answers:
To answer this question, it is enough to find the volume of a rectangular prism.
The volume of a rectangular prism is:
Where,
Ab: base area
h: height
The area of the base is:
Where,
w: width
l: long
We observe that the area of the base is a rectangle, therefore, the section parallel to the base is also a rectangle.

Answer:
c = -9
Step-by-step explanation:
Knowing that -2 is a root, you can do the synthetic division with an unknown value for c. Then solve for the value of c that makes the remainder be zero. See the attachment for the work.
The second attachment shows that (x+2) is a factor of the resulting cubic.
