How do I solve this equation?
Gnom [1K]

2x(4-x)^{-1/2}-3(4-x)^{1/2}=(4-x)^{-1/2}\bigg(2x-3(4-x)\bigg)

We effectively rewrite the equation as

\dfrac{5x-12}{(4-x)^{1/2}}=0

In order for the LHS to be defined, we need to restrict 4-x>0, or x. Now, the LHS will vanish when the numerator is 0, which happens for

5x-12=0\implies5x=12\implies x=\dfrac{12}5

This value is indeed smaller than 4, so the solution is x=\dfrac{12}5.

A rectangle has an area of 84 square feet. the length is twice the width. draw a rectangle and draw a line dividing it in two to
algol13

The width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.

<h3>How to determine the dimensions</h3>

The formula for determining the area of a rectangle is expressed as;

Area = width × length

Given that;

  • Area = 84 square feet
  • length = 2w

Let's substitute into the formula

84 = w(2w)

84 = 2w²

Divide both sides by 2

84/ 2 = w²

42 = w²

Take square root of both sides

w = √42

w = 6.4 feet

Length = 2w = 2 × 6. 4 = 12. 96 meters

Thus, the width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.
