Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inches? Select three options.. A right rectangular prism with length 15 inches, width of 8 inches, and height of 6 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.
A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
Describe two methods that can be used to find the area of the composite figure.

pls help

Step-by-step explanation:

A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.

A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches. (provided "passes through" means "includes the opposite 6 inch sides in entirety")

There are not two methods to figure the area. Only one which is summing the areas of the six faces.

A = ab + ab + bc + bc + ca + ca  

This can be written in several means such as by doubling the sum of areas of three unique faces

A = 2(ab + bc + ca)

or by adding twice the base area to the perimeter of the base times the height. A = 2ab + c(2a + 2b)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
