12x^2+20=50 what is x
LenaWriter [7]

Answer: x=1.5811389999999999 , or 1.59

Step-by-step explanation:

First, Subtract 20 from both sides.

      12x2+20−20=50−20

      12x2=30

 Then, Divide both sides by 12:

12x^2/12 = 30/12

⇒ you get : x^2 = 5/2

After, Take square root.

x= ± √ 5/2

Finally you answer is going to be =1.5811389999999999 OR, 1.59

* Hopefully this helps:) Mark me the brainliest:)

patriot [66]

9514 1404 393

Answer:

  15.71 units

Step-by-step explanation:

The arc length is given by the formula ...

  s = rθ

where r represents the radius, and θ represents the central angle in radians.

The angle of 60° is π/3 radians, so the arc length is ...

  s = 15(π/3) = 5π ≈ 15.71 . . . units

  LN ≈ 15.71 units

__

<em>Note</em>: if you use 3.14 for π, you will get 15.70.
