a rectangular pool has an area of 640 square feet. the is 12 feet shorter than the width. the length of the pool is feet and the
Ray Of Light [21]

Given:

Area of rectangular pool = 640 square feet

The length is 12 feet shorter than the width.

To find:

The length and width of the pool.

Solution:

Let width of the pool = x feet

Then, Length of the pool = (x-12) feet

Area of a rectangle is

Area=length\times width

Area=(x-12)\times x

Area of pool is 640 square feet. So,

(x-12)x=640

x^2-12x-640=0

Splitting the middle term, we get

x^2-32x+20x-640=0

x(x-32)+20(x-32)=0

(x+20)(x-32)=0

Using zero product property, we get

x=-20,32

Dimensions cannot be negative. So, x=32.

Now,

Width of the pool = 32 feet

Length of the pool = 32-12 = 20 feet

Therefore, the length of the pool is 20 feet and width is 32 feet.

I need help please and thank you
monitta

Answer: 8.

Step-by-step explanation:

Simplify the equation by getting rid of the exponents.

\frac{(10 * 10) -(100 + (8*8))}{2*2*2}

Which is then simplified to:

\frac{100 - 100 + 64}{8}, or 64/8. Divide to get your answer.
