X square+3x-40=0 factorise it​

Answer»

ANSWER:

X = 5 and -8

Step-by-step EXPLANATION:

x²+3x-40 = 0

(x-5)(x+8) = 0

x-5 = 0 => x = 5

x+8 = 0 => x = -8

or

x²+3x-40 = 0

x²+8x-5x-40 = 0

x(x+8)-5(x+8) = 0

(x-5)(x+8) = 0

x-5 = 0 => x = 5

x+8 = 0 => x = -8

Solve the quadratic equation z^2+4iz+4=0

Answer»

Answer:

I THINK this MUST be helpful

Step-by-step explanation:

Simplifying

z2 + 4iz + -4 = 0

Reorder the TERMS:

-4 + 4iz + z2 = 0

Solving

-4 + 4iz + z2 = 0

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4iz + 4 + z2 = 0 + 4

Reorder the terms:

-4 + 4 + 4iz + z2 = 0 + 4

Combine like terms: -4 + 4 = 0

0 + 4iz + z2 = 0 + 4

4iz + z2 = 0 + 4

Combine like terms: 0 + 4 = 4

4iz + z2 = 4

Add '-1z2' to each side of the equation.

4iz + z2 + -1z2 = 4 + -1z2

Combine like terms: z2 + -1z2 = 0

4iz + 0 = 4 + -1z2

4iz = 4 + -1z2

Divide each side by '4z'.

i = z-1 + -0.25z

Simplifying

i = z-1 + -0.25z

If 3 tan α = 4 ,and 2 SEᑕ α = 3 k+ 1 ,then find k if α is acute .​

Answer»

Step-by-step explanation:

3 tanα=4

tanα= 4/3

secα= 3k+1

We KNOW that sec²-tan²=1

so,

(3k+1)²-(4/3)²=1

(3k+1)²= 1+(4/3)²

(3k+1)²= 1+16/9

(3k+1)²= 25/9

on taking root both SIDE we GET

3k+1= ±5/3

3k+1= 5/3

3k= 5/3-1

3k= 2/3

k= 2/9

3k+1= -5/3

3k= -5/3-1

3k= -8/3

k= -8/9

How many sides does a regular polygon have if each of its interior angles is 140 ?​

Answer»

\large\underline{\sf{Solution-}}

GIVEN that,

↝  Each interior angle of a regular polygon is 140°.

Let assume that

↝ Exterior angle of a regular polygon be .

and

↝ Number of SIDES of a regular polygon be 'n'.

We know,

Interior angle and exterior angle of a regular polygon is connected by the relationship

\boxed{ \tt{ \: Interior \: angle + Exterior \: angle = 180 \degree \: }}

So, using this, relationship

\rm :\longmapsto\:140\degree + x = 180\degree

\rm :\longmapsto\:x = 180\degree - 140\degree

\rm \implies\:\boxed{ \tt{ \: x \:  =  \: 40\degree \: }}

Further, We know that

Number of sides and exterior angle of a regular polygon is connected by the relationship

\boxed{ \tt{ \: Number \: of \: sides =  \frac{360\degree}{Exterior \: angle}  \: }}

So, using this release, we GET

\rm :\longmapsto\:n \:  =  \: \dfrac{360\degree}{40\degree}
