Calculate the area of the composite figure.

Check the picture below.

115.5 square inches.

Step-by-step explanation:

We have been given a composite figure. We are asked to find the area of our given composite figure.

We can see that our given figure consists a rectangle and a triangle.

Therefore, the area of our given composite figure is 115.5 square inches.

true

explanation:

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
