Use the quadratic formula to solve for x.

Mathematics

ivann1987 [24]3 years ago

Answer:

x = 1/3 + sqrt(5/2)/3 or x = 1/3 - sqrt(5/2)/3

Step-by-step explanation:

Solve for x:

6 x^2 - 4 x = 1

Divide both sides by 6:

x^2 - (2 x)/3 = 1/6

Add 1/9 to both sides:

x^2 - (2 x)/3 + 1/9 = 5/18

Write the left hand side as a square:

(x - 1/3)^2 = 5/18

Take the square root of both sides:

x - 1/3 = sqrt(5/2)/3 or x - 1/3 = -sqrt(5/2)/3

Add 1/3 to both sides:

x = 1/3 + sqrt(5/2)/3 or x - 1/3 = -sqrt(5/2)/3

Add 1/3 to both sides:

Answer: x = 1/3 + sqrt(5/2)/3 or x = 1/3 - sqrt(5/2)/3

Aleks [24]

Answer:

254.34

Step-by-step explanation:

Given the circumfrence we can find the diameter b dividing by pi which will get us 18. We can then divide by 2 to get 9 which is our radius. To get the area we will square our radius :81 and multiply it by pi to get 254.34.

BabaBlast [244]

Answer:

Step-by-step explanation:

To prove the triangle angle sum theorem,

We will do a construction by drawing a line PQ passing through point F and parallel to line DE.

                Statements                              Reasons

1). ∠PFD + ∠QFD = 180°                     1). linear pair postulate

2). ∠QFD = ∠QFE + ∠EFD                 2). Angle addition postulate

3). ∠PFD + ∠QFE + ∠EFD = 180°       3). Substitution property

4). ∠PFD ≅ ∠FDE                               4). Alternate interior angles

    ∠QFE ≅ ∠DEF                                

5). ∠FDE + ∠DEF + ∠EFD = 180°       5). Substitution property

Hence sum of interior angles of ΔDEF is 180°.
