Answer:

\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}

Step-by-step explanation:

Given equation to us is ,

\green{\implies x^2+\dfrac{1}{x}=4 }

So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,

\implies x^2 +\dfrac{1}{x}=4

Taking x as LCM ,

\implies \dfrac{x^2.x + 1 }{x}= 4

Transposing x to RHS .

\implies x^3 + 1 = 4x

Putting all terms in LHS

\boxed{\bf \implies x^3 - 4x - 1 = 0 }

Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

<h3><u>Hence</u><u> </u><u>the </u><u>given </u><u>equation </u><u>is</u><u> </u><u>not</u><u> </u><u>a</u><u> </u><u>quad</u><u>ratic</u><u> equation</u><u> </u><u>.</u></h3>

9. A blueprint of a house plan uses a scale in
nata0808 [166]

Answer:

The length on the blueprint for an actual length of 65 feet is 16\frac{1}{4}\ inches

Step-by-step explanation:

Given:

Scale of the blueprint is \frac{1}{4}\ in=1\ foot

Length of one side of the house is 65 feet.

Now, as per given data;

1 foot in actual = \frac{1}{4}\ in on the blueprint.

Therefore, using unitary method, we can find find the length on the blueprint for an actual length of 65 feet by multiplying 65 and \frac{1}{4}. Therefore,

Length on the blueprint for 65 feet is given as:

=\frac{1}{4}\times 65\\\\=\frac{65}{4}\\\\=16\frac{1}{4}\ inches

Therefore, the length on the blueprint for an actual length of 65 feet is 16\frac{1}{4}\ inches

Please (Parentheses)

Excuse (Exponents)

My (Multiication)

Dear (Division)

Aunt (Addition)

Sally (Subtraction)
