Harlamova29_29 [7]

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

1. Chuck wants to draw three-dimensional figures whose lateral faces are rectangles. He says he can draw prisms and pyramids. Do you agree

No, I do not agree because:

The lateral faces of a pyramid are triangles
The lateral faces of a prism are rectangles

2. Part B. Chuck says that he can draw a cylinder on his polyhedron poster because it has a pair of bases that are congruent.

No, do not agree because:

A cylinder has two congruent bases but it is not a polyhedron while a cylinder has a curved surface when a polyheron has faces that are polygons

Hope it will find you well.

The rational expressions [(x² + 16xz + 64z²)/(x²z + 8xz²)] ÷ [(x² + 5xz + 24z²)/(x⁴z - 9x²z³)] can be simplified as; x(x - 3z)

<h3>How to divide algebraic expressions?</h3>

We want to divide the rational expressions;

[(x² + 16xz + 64z²)/(x²z + 8xz²)] ÷ [(x² + 5xz + 24z²)/(x⁴z - 9x²z³)]

Let us break down the expressions one after the other;

(x² + 16xz + 64z²) can be expressed as;

(x + 8z)²

Likewise, (x²z + 8xz²) can be expressed as;

xz(x + 8z)

Thus;

[(x² + 16xz + 64z²)/(x²z + 8xz²)] is;

(x + 8z)²/(xz(x + 8z)) = (x + 8z)/xz

(x² + 5xz + 24z²) can be expressed as;

(x + 3z)(x + 8z)

Similarly;

(x⁴z - 9x²z³) can be expressed as;

x²z(x² - 9z²)

Thus;

[(x² + 5xz + 24z²)/(x⁴z - 9x²z³)] can be expressed as;

(x + 3z)(x + 8z)/(x²z(x² - 9z²))

Then our main expression can now be expressed as;

[(x + 8z)/xz] ÷ (x + 3z)(x + 8z)/(x²z(x² - 9z²))

This can be rewritten as;

[(x + 8z)/xz] * [(x²z(x² - 9z²))]/((x + 3z)(x + 8z))

x(x² - 9z²)/(x + 3z)

This can further be simplified as;

x(x + 3z)(x - 3z)/(x + 3z) = x(x - 3z)
