Quadratic equation

Murrr4er [49]

Answer:

Step-by-step explanation:

x - age of a son three years ago

3x - age of a father three years ago

x + 3 - age of the son now

3x + 3 - age of the father now

x + 3 + 5 - age of the son in five years time

3x + 3 + 5 - age of the father in five years time

in five years time, the father will be twice as old as his son, so:

3x + 3 + 5 = 2(x + 3 + 5)

3x + 8 = 2x + 16

3x - 2x = 16 - 8

x = 8

x + 3 + 4 - age of the son in four years time

8 + 3 + 4 = 15

3x + 3 + 4 - age of the father in four years time

3×8 + 3 + 4 = 31

the sum of their ages in four years time:

15 + 31 = 46

M is a midpoint of BC so:

$M=\left(\dfrac{\boxed{2}\boxed{a}+a}{\boxed{2}},\dfrac{\boxed{0}+b}{2}\right)=\left(\dfrac{\boxed{3}\boxed{a}}{\boxed{2}},\dfrac{\boxed{b}}{\boxed{2}}\right)$

Length of MA:

$MA=\sqrt{\left(\dfrac{\boxed{3}a}{2}\boxed{-}\boxed{0}\right)^2+\left(\dfrac{\boxed{b}}{2}\boxed{-}\boxed{0}\right)^2}=\\\\\\=
\sqrt{\left(\dfrac{\boxed{3}a}{\boxed{2}}\right)^2+\left(\dfrac{b}{2}\right)^2}=\sqrt{\dfrac{\boxed{9}a^2}{\boxed{4}}+\dfrac{\boxed{b}^2}{\boxed{4}}}$

Length of NB:

$NB=\sqrt{\left(\dfrac{a}{2}\boxed{-}\boxed{2}a\right)^2+\left(\dfrac{b}{2}\boxed{-}\boxed{0}\right)^2}=\\\\\\=\sqrt{\left(\dfrac{a}{2}\boxed{-}\dfrac{\boxed{4}\boxed{a}}{2}\right)^2+\left(\dfrac{b}{2}-\boxed{0}\right)^2}=\\\\\\
\sqrt{\left(\dfrac{-3a}{2}\right)^2+\left(\dfrac{b}{\boxed{2}}\right)^2}=\sqrt{\dfrac{\boxed{9}a^2}{\boxed{4}}+\dfrac{\boxed{b}^2}{\boxed{4}}}$

Addition of unlike fractions 5/3 + 7/4

Maru [420]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{3 \frac{5}{12}}}}}}$

Step-by-step explanation:

$\star{ \sf{ \: \: \frac{5}{3} + \frac{7}{4}}}$

Convert the given fractions into like fractions.

To do so, Take the L.C.M ( Least Common Multiple ) of 3 and 4.

To find out the L.C.M of given numbers,

First of all, find the prime factors of each numbers.

3 = 3 × 1

4 = 2 × 2 × 1

Take out the common prime factor i.e 1

Also take out the other remaining prime factors i.e 2 , 2 and 3

Now, multiply those all prime factors and obtain L.C.M

= 1 × 2 × 2 × 3 = 12

L.C.M of 3 and 4 = 12

$\dashrightarrow{ \sf{ \frac{5 \times 4 + 7 \times 3}{12}}}$

$\dashrightarrow{ \sf{ \frac{20 + 21}{12}}}$

Add the numbers : 20 and 21

$\dashrightarrow{ \sf{ \frac{41}{12}}}$

Convert the improper fraction into mixed fraction

$\dashrightarrow{ \boxed{\sf{3 \frac{5}{12} }}}$

Remember : While performing the addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus , obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction.

Hope I helped!

Best Regards!
