Answer:

k=0.106383

Step-by-step explanation:

Let's solve your equation step-by-step.

12=4.7k+11.5

Step 1: Flip the equation.

4.7k+11.5=12

Step 2: Subtract 11.5 from both sides.

4.7k+11.5−11.5=12−11.5

4.7k=0.5

Step 3: Divide both sides by 4.7.

4.7k

4.7

0.5

4.7

k=0.106383

Solve for unknown in 2x^3+6x^2-20x=0

Licemer1 [7]

The solution of x is x = 0, x =2 and x = -5

<h3>How to solve for the unknown?</h3>

The equation is given as:

2x^3+6x^2-20x=0

Factor out x

x(2x^2+6x-20)=0

Split the equation

x = 0 or 2x^2+6x - 20=0

Solve for x in 2x^2+6x - 20=0

Expand the equation

2x^2 + 10x - 4x - 20 = 0

Factorize the equation

(2x - 4)(x +5) = 0

Split the equation

2x - 4 = 0 and x + 5 = 0

Solve for x

x =2 and x = -5

Hence, the solution of x is x = 0, x =2 and x = -5
