Answer:

71.25 pounds

Step-by-step explanation:

I'd put it all in a ratio first

So it would look something like this :

4. : 19

1. : 4. 75. ( I just divided them both by 4 so wp is 1)

15. : 71. 25. ( I multiplied them by 15 )

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
