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}

Can someone help its algebra?
aalyn [17]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle , that is

3x + 2x + 6 + 6x - 3 ( simplify by collecting like terms )

= 11x + 3

Given the perimeter = 36 units , then

11x + 3 = 36 ( subtract 3 from both sides )

11x = 33 ( divide both sides by 11 )

x = 3

Then

base = 2x + 6 = 2(3) + 6 = 6 + 6 = 12 units

height = 3x = 3(3) = 9 units

hypotenuse = 6x - 3 = 6(3) - 3 = 18 - 3 = 15 units

Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?
Lesechka [4]

Complete Question

Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?

a) She cut the wood into pieces that are each 1/3 meter long.

b) She cut the wood into pieces that are each 1/2 meter long.

c) She cut the wood into pieces that are each 1 meter long.

d) She cut the wood into pieces that are each 1 1/2 meter long.

Answer:

d) She cut the wood into pieces that are each 1 1/2 meter long.

Step-by-step explanation:

Marla sawed a 12-meter wood plank into 8 equal pieces.

Hence,

8 equal pieces = 12 meter

1 equal pieces = x meter

Cross Multiply

8 × x = 1 × 12

x = 12/8 meters

x = 3/2 meters long

x = 1 1/2 meters long.

Therefore, Option d is the correct Option
