Answer:
94 cubic units
Step-by-step explanation:
The volume of this parallelepiped (the product of area of its base and height) is equal to the absolute value of the scalar triple product 
Since

we have

<span>volume of a cube
V= a^3 = 1^3 = 1

</span><span>D . 1 cubic foot</span>
Answer:
a) 
b)
c) 
Step-by-step explanation:
We want to simplify

Let :

Square both sides of the equation:

Expand the RHS;

Compare coefficients on both sides:


Solve the equations simultaneously,


Solve the quadratic equation in b²

This implies that:

When b=-3,

Therefore

We want to rewrite as a product:

as a product:
We rearrange to get:

We factor to get:

Factor again to get;

We rewrite as difference of two squares:

We factor the difference of square further to get;

c) We want to compute:

Let the numerator,

Square both sides of the equation;

Compare coefficients in both equations;

and

Put equation (2) in (1) and solve;



When b=-1, a=-2
This means that:

This implies that:
