Answer:

x = 3/2; x = -1/2

Step-by-step explanation:

6x² - x - 2 = 0

⇔ 6x² - 4x + 3x - 2 = 0

⇔ (6x² - 4x) + (3x - 2) = 0

⇔ 2x(3x - 2) + (3x - 2) = 0

⇔ (3x - 2)(2x + 1) = 0

⇔\left \{ {{3x - 2=0} \atop {2x + 1=0}} \right.

⇔\left \{ {{3x=2} \atop {2x=-1}} \right.

⇔\left \{ {{x=2/3} \atop {x=-1/2}} \right.

Answer:

x 1=  \frac{ + 1 +  \sqrt{  { (- 1)}^{2}  - 4 \times 6 \times ( - 2)}  }{ 12} =  \frac{8}{12}  \\ x =  \frac{ + 1  -   \sqrt{  { (- 1)}^{2}  - 4 \times 6 \times ( - 2)}  }{ 12} =  \frac{ - 6}{12}

Answer:

read the explanation, i'm not gonna answer this one for you, but instead I want you to try this on your own.

Step-by-step explanation:

divide the 360 by each percentage, and if you dont know how to do that, there are videos out there, i <em>would</em> explain it <em>but </em>i dont have much time to write all of that. after you get each number from dividing 360 by each percentage <em>individually </em>you will add up the <u>needed</u> numbers. that will give you your answer! have a nice day :D

If anyone can solve this quickly I will give brainly
Nataly [62]

Answer:

m∠BFE  = 171º

BE = 219º

Step-by-step explanation:

∠BFE is supplementary to ∠EFC

m∠BFE  = 180 - 9

m∠BFE  = 171º

--------------------------

The angle between two chords is equal to half the sum of the intercepted arcs:

∠BFE = (DC + BE)2

171 = (123 + BE)/2

342 = 123 + BE

219º = BE
