Mr. Lin is four times as old as his daughter. In 4 years he will be three times as old as his daughter. How she is his daughter

Kobotan [32]

Answer:

The present age of Mr. Lin's daughter = 8 years old.

The present age of Mr. Lin = 32 years old

Step-by-step explanation:

Let the present age of Mr. Lin's daughter = x yrs old

So, the present age of Mr. Lin = 4 times daughter's age = (4 x) yrs

Now, age of daughter after 4 years = (x + 4) yrs

and the age of Mr. Lin after 4 years= ( 4x + 4) years

Also, ( 4x + 4) = 3 times (x+4)

According to the question:

4x + 4 = 3(x+4)

or, 4x + 4 = 3x + 12

⇒ 4x - 3x = 12 -4

or, x = 8

Hence, the present age of Mr. Lin's daughter = 8 years old.

and the present age of Mr. Lin = 4 x = 4 x 8 = 32 years old

Subtraction of the polynomial fractions $\frac{7t^{2} -t -4 }{t^{2} -25} -\frac{6t^{2}+12t -44}{t^{2} -25}$ is $\frac{(t-8)}{(t+5)}$

How are the polynomial fractions subtracted?

Since the denominators of the fractions are same,

$\frac{({7t^{2} -t -4 }) -({6t^{2}+12t -44})}{t^{2} -25} \\\\=\frac{7t^{2} -t -4-6t^{2}-12t +44}{t^{2} -25} \\\\=\frac{t^{2} -13t +40 }{t^{2} -25}$

By, factorization of the polynomial fractions,

$\frac{t^{2} -13t +40 }{t^{2} -25}\\\\=\frac{(t-5)(t-8)}{(t+5)(t-5)}\\\\=\frac{(t-8)}{(t+5)}$

What are polynomial fractions?

Polynomial fraction is the result of dividing one polynomial by another.

By factorizing and reducing them to the lowest terms, a polynomial fraction can be made simpler when a polynomial appears in either the numerator or the denominator.

A fraction in which either the numerator or the denominator are polynomials is the same as a rational expression.

Factoring the polynomial entirely within the numerator and the denominator is necessary in order to factor it completely.
