Answer:

It is a rational number.

Step-by-step explanation:

A number is only irrational if it has a decimal that never ends and doesn't have a pattern. So a number like Pi (3.141592653589...) is irrational while a number like 1/3 (0.33333333...) is rational.

Hi :)

Below is the difference between rational & irrational numbers

<h2>______________</h2><h3>RATIONAL</h3>

A number that can be expressed in $\sf{\dfrac{p}{q}}$ form, where $\large\boldsymbol{q\ne0}$

Evidently,

An irrational number is a number that cannot be expressed in $\sf{\dfrac{p}{q}}$ form

Let's test the given number, $\boldsymbol{3\dfrac{1}{4}}$

Well isn't it already in $\sf{\dfrac{p}{q}}$ form? It is.

Thus

$\longrightarrow\darkblue\boldsymbol{3\dfrac{1}{4}\:is\:rational}$

The width of a rectangle is the length minus 7 units. The area of the

AleksandrR [38]

Answer:

8 units

Step-by-step explanation:

here's your solution

=> let the length of rectangle be X

=> then width = x - 7

=> area = 8units

=>> area = length*width

=> area = x (x-7) = 8

=> x^2 - 7 = 8

=> now, x^2 - 7x - 8 = 0

=> factories the above equation by middle term split

=> x^2 - 7x - 8

=> x^2 - 8x + x - 8

=> take the common

=> x(x - 8) + 1(x - 8)

=> (x + 1) (x - 8)

neglect (x + 1) because this will in negative for X

=> x - 8 = 0

=> x = 8

=>so, x = 8

=>length = 8 units

In isosceles pqr with base , pq = 2x + 3, and pr = 9x - 11. what is the value of x?

Anon25 [30]

First, draw and label a rough sketch of an isosceles triangle. Now put in the values of pq=2x+3 and pr=9x-11

You know that the triangle is isosceles, therefore, the sides pq and pr are identical.

Now, make the equations equal to each other to find the value of x.

2x+3=9x-11
3+11=9x-2x
14=7x
14/7=x
2=x

Therefore the value of x=2.

Hope I helped :)
