Rational expressions are those that have fractional terms. We state restrictions because it may cause the equation to be undefined in some values of x. The most common restriction for rational expressions is N/0. This means any number divided by zero is undefined.

<h3>What is rational expressions and examples?</h3>

A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions.

To find the restrictions on a rational function, find the values of the variable that make the denominator equal 0.

Find the value of x in each case. Give reasons to justify your solutions! XW ∥ YZ
Charra [1.4K]

Answer:

The answer is "19".

Step-by-step explanation:

In this question, the graph file is missing which is defined in the attached file please find it.

When YZ and XW were identical,  

\angle XWY =\angle WYZ \ \  \text{(Alternate Angles)}

\angle XWY = 2x

Because the angles are all 180 degrees in either a triangle:

\to (3x - 5) + 90 + 2x = 180\\\\\to 3x - 5 + 90 + 2x = 180\\\\ \to 5 x + 85= 180 \\\\ \to 5 x = 180-85 \\\\ \to 5x = 95 \\\\ \to x= \frac{95}{5} \\\\ \to x = 19

One pound of grout is enough to grout a tiled area that is 110 sq. Ft. Alyssa's kitchen counter is made up of two rectangular se
Ratling [72]

Answer:

(10.3(2.5)+3.1(2))\div 110

Step-by-step explanation:

A_1 = Area of 1st rectangle = (10.3\times 2.5)\ \text{ft}^2

A_2 = Area of 2nd rectangle = (3.1\times 2)\ \text{ft}^2

1\ \text{pound of grout}=110\ \text{ft}^2

\Rightarrow 1\ \text{ft}^2=\dfrac{1}{110}\ \text{pound of grout}

The number of pounds required for the counter top is

\text{Total area}\times \text{The amount of grout used in 1 ft}^2

=A_1+A_2\times \dfrac{1}{110}=(10.3(2.5)+3.1(2))\times \dfrac{1}{110}\\ =(10.3(2.5)+3.1(2))\div 110

The required expression is (10.3(2.5)+3.1(2))\div 110.
