2x-4y=20 what is the value of y

ra1l [238]

Answer: 20-2x/-4

Step-by-step explanation:

To actually solve for y as a number, you need two equations.

For this case move the 2x to the other side, making the equation -4y=20-2x.

Then divide by -4 on each side making the equation y=20-2x/-4.

Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive a

marysya [2.9K]

Answer:

V = 6x²(2x - 5)

Step-by-step explanation:

Factor the dimensions, that is

24x² + 6x = 6x(4x + 1) ← common factor of 6x

x² - x = x(x - 1) ← common factor of x

The product lwh can now be written

V = $\frac{6x(4x+1)}{x-1}$ × (2x - 5) × $\frac{x(x-1)}{4x+1}$

Cancel the factors (4x + 1) and (x - 1) from the numerators/ denominators

V = 6x × x × (2x - 5) = 6x²(2x - 5) ← in factored form
