Genrish500 [490]

Answer:

The height of the container is 4 feet.

Step-by-step explanation:

A container has the format of a rectangular prism.

It has three dimensions: width(w), length(l), height(h).

The volume is:

$V = w*l*h$

In this question:

$w = 45, l = 50, V = 9000$

We have to find the height(length and width are in feet, volume in cubic feet, so the height will be in feet).

$V = w*l*h$

$9000 = 45*50*h$

$h = \frac{9000}{45*50}$

$h = 4$

The height of the container is 4 feet.

What is the difference of the polynomials?

Vilka [71]

Answer:

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

Step-by-step explanation:

We want to simplify;

$(8r^6s^3-9r^5s^4+3r^4s^5)-(2r^4s^5-5r^3s^6-4r^5s^4)$

We expand the bracket to obtain;

$8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4r^5s^4$

We now group the like terms to obtain;

$8r^6s^3-9r^5s^4+4r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6$

We now simplify to get;

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

The correct answer is C
