The figure below is a net for a triangular prism. Side a = 47 inches, side b = 13 inches, side c = 33 inches, and altitude d = 23 inches. What is the surface area of this figure? Note: Figure is not drawn to scale. A. 2,914 square inches B. 3,161 square inches C. 2,550 square inches D. 2,121 square inches

i suppose it should be (y=2x-5)

step-by-step 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
