Answer 1

$\huge\mathtt\pink{Answer}$

Let each equal side of an isosceles triangle ABC be x cm.

Then, its perimeter =AB+BC+CA=(x+

3

4

+x) cm =(2x+

3

4

) cm

But it is given that the perimeter of the triangle =4

15

2

cm =

15

62

cm

Therefore, 2x+

3

4

=

15

62

⇒30x+20=62 ...[On multiplying both sides by 15]

⇒30x=62−20

⇒30x=42

⇒x=

30

42

=

Thus, each equal side of the isosceles traingle is of 1

2

cm.

Answer 2

Answer:

p(x) = a * x ^ 3 + bx - 1

g(x)=6x^ 2 -3x-1=0(as x is a root)

x=(3 pm sqrt 33)/12;

x=(3+ sqrt 33)/12 or x=(3- sqrt 33)/12
