a rectangle swimming pool is 4 ft deep. one side of the pool is 2.5 times longer than the other. the amount of water needed to f
mojhsa [17]

Find the are of the pool by dividing the volume by the depth:

1960 / 4 = 490

The pool is 490 square feet.


Area is found by multiplying the length by the width.

Let the width = X

We are told the length is 2.5X ( 2.5 times longer)


So we now have 2.5x * x = 490


2.5x * x = 2.5x^2


Now we have 2.5x^2 = 490


Divide both sides by 2.5:

x^2 = 490/2.5

x^2 = 196

find X by taking the square root of 196:

x = √196

x = 14


The width is 14 feet

The length is 2.5 * 14 = 35 feet

Consider 8x2 - 48x = -104.
ki77a [65]

Answer:

3+ 2\mathbf{i}

3- 2\mathbf{i}

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

8x^2-48x=-104

Divide by 8:

x^2-6x=-13

Now complete the squares so the left side is a perfect square of a binomial:

x^2-6x+9=-13+9=-4

Factoring the perfect square:

(x-3)^2=-4

Taking the square root:

x-3=\sqrt{-4}

The square root of a negative number is an imaginary number:

x-3=\pm 2\mathbf{i}

Solving for x:

x=3\pm 2\mathbf{i}

The solutions are:

3+ 2\mathbf{i}

3- 2\mathbf{i}
