Answer» Answer: We can form an EQUATION as follows- 224 = x + 2X + 4X ( the first part is x, second part is 2x and the third part is 2×2x=4x) 224 = 7x x= 224/7 = 32 Therefore, first part = 32 second part =2×32 = 64 third part = 4×32=128

23.

divide 224 into 3 parts so that the second will be twice the first and third will be twice the second

Answer»

Answer:

We can form an EQUATION as follows-

224 = x + 2X + 4X

( the first part is x, second part is 2x and the third part is 2×2x=4x)

224 = 7x

x= 224/7 = 32

Therefore, first part = 32

second part =2×32 = 64

third part = 4×32=128

Find the zeros of the quadratic polynomial 5x^2+12x+7and verify the relationship between the zeros and the coefficients

Answer»

$\mathfrak{\large{\underline{\underline{<klux>GIVEN</klux>:-}}}}$

Quadratic eqn:- $\bold{ 5 {x}^{2} + 12x + 7}$

$\mathfrak{\large{\underline{\underline{To find:-}}}}$

⭐Relation between their ZEROS and coefficient.

$\mathfrak{\large{\underline{\underline{Solution:-}}}}$

Let a = 5 , b = 12 and c = 7

Let $\alpha$ and $\beta$ be the roots of the given quadratic equation.

By USING MIDDLE splitting term,

$\implies$ $\bold{5 {x}^{2} + 12x + 7}$

$\implies$ $\bold{ 5 {x}^{2} + 5x + 7x + 7= 0}$

$\implies$ $\bold{5x( x + 1) + 7(x + 1) = 0}$

$\implies$ $\bold{(5x + 7)(x + 1) = 0 }$

$\implies$ $\bold{x = \frac{ - 5}{7} or \: x = - 1 }$

Now, $\alpha = \frac{ - 5}{7}$ and $\beta = -1$

The relationship between sum of zeroes and coefficient of Quadratic polynomial is given by :-

★ $\boxed{\sf{ \alpha + \beta = \frac{ - b}{a} }}$

$\implies$ $\bold{ \frac{ - 5}{7} + 1 = \frac{ - 12}{5} }$

$\implies$ $\bold{ \frac{ - 7 - 5}{ 5} = \frac{ - 12}{5} }[/tex][tex]\implies$ $\bold{ \frac{-12}{5} = \frac{-12}{5} }$

L. H. S = R. H. S verified.

Now,

Relation between products of zeroes and their coefficient is given by :-

★ $\boxed{\sf{ \alpha \beta = \frac{c}{a} }}$

$\implies$ $\bold{ \frac{ - 7}{5} \times - 1 = \frac{7}{5} }$

$\implies$ $\bold{ \frac{7}{5} = \frac{7}{5} }$

L. H. S = R. H. S hence ,verified..

A is equal to 60% of the 40% b, how much is a: b

Answer»

SINCE, A = 60% of 40% of B

:. A =B*60/100 *40/100

:. A =6B/25

:. A/B = 6/25
