What lengths would allow you to calculate the volume of the oblique pyramid with a square base? check all that apply.

we know that

the volume of the oblique pyramid with a square base is equal to

where

B is the area of the base

h is the height of the pyramid

In this problem

The area of the base is

The two formulas to calculate h are

Applying the Pythagoras Theorem

------>

------>

therefore

the answer is

AB and EF

AC, CB and EF

AD, DB and EF

Step-by-step explanation:

(a)

let, f(x) = 2x+1 & g(x) = 2x+2

So, f(x).g(x) = (2x+1).(2x+2) = 4x² + 6x + 2 = 2x+2 in

So, product of two 1 degree polynomials is a 1-degree polynomial in

(b)

let, f(x) = 2x³ - 3x² + 5x + 7 & g(x) = -2x³ + 3x² + x + 3 be two polynomials in R[x]

So, f(x) + g(x) = 6x + 10, which is a polynomial of degree 1 in R[x]

(c)

this is not possible, since, if f & g are 2 polynomials in any polynomial ring S, then, we always have,

deg(f.g) <= deg(f) + deg(g)

So, deg(f.g) = 5 (as desired) but, deg(f) + deg(g) = 2+2 = 4 but, 4 < 5

So, this is not possible.

So, no such example exists.
