Brody’s town is building a pool based on a scale drawing that is 20 centimeters by 10 cemtimeters and uses the scale 1 cemtimeter : 250 cemtimeters. what is the area of the pool in square meters?

Area of the pool is 1250 square meters.

Step-by-step explanation:

Given:

1 cm on scale is 250 cm in actual.

Therefore, 20 cm on scale is

10 cm on scale is

Also, we know that,

Therefore,

Area of the pool is given as,

Therefore, the area of the pool is 1250 square meters.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
