The area of rectangular slab of concrete (4x²-2x) square feet. if it is 2x feet wide, what is the length, in feet?​

Sagot :

Answer:

2x – 1

Explanation:

Combine the equation into this - 4x2−2x=2x(2x−1)

Now go from there (2x * 2x - 1, etc.) Simplify the equation.

Then, you end up with 2x-1.

Answer:

The length is 2x - 1

Step-by-step explanation:

Length of a rectangle = Area ÷ width

ℓ = A ÷ b

ℓ = 4x² - 2x ÷ 2x

When factored, 4x² - 2x becomes 2x(2x - 1)

ℓ = 2x(2x - 1) ÷ 2x

ℓ = x(2x - 1) ÷ x

ℓ = 2x - 1
