Mathematics

3x² -x+4=0

We can use quadratic formula
a=3, b= -1, c=4
 x=  \frac{-b+/- \sqrt{b^{2}-4ac} }{2a}  
\\ \\ x= \frac{1+/- \sqrt{1-4*3*4} }{2*3} 
\\ \\ x =  \frac{1+/- \sqrt{-47} }{6} 

This equation does not have real  roots, it has only 2 imaginary roots.

x= \frac{1+ \sqrt{47}i }{6} 
\\ \\ x=  \frac{1- \sqrt{47}i }{6}

Find the value of x​
damaskus [11]

Answer:

x=12

Step-by-step explanation:

First, note that the angles shown are vertical angles. In other words, the two equations are equivalent to each other.

Therefore, set the equations equal to each other and solve for x;

6x+7=8x-17

Add 17 to both sides:

6x+24=8x

Subtract 6x from both sides:

24=2x

Divide both sides by 2:

x=12

Therefore, the value of x is 12.

And we're done!

Red flowers = 1/8

Purple = 1/4

(1/8 + 1/4) = (1 + 2) / 8 = 3/8

Fraction left :

1 - 3/8 =. 5/8

Pink flowers :

1/4 of fraction left ;

1/4 * 5/8 = 5/32

Number of pink flowers

Total number of flowers = 128

5/32 * 128
