Question

A United States flag is sometimes folded into a triangle shape and displayed in a triangular display case. If a display case has dimensions shown in inches, write a polynomial expression that represents the area of wall space covered by the display case.

Answer 1

Step-by-step explanation:

area of ∆ = .5*b*h

b= x+5

h= x-5/2

let's do (x+5) * (x-5/2)

x^2+5x-5/2x-25/2

x^2+5/2x-25/2

area = .5x^2+5/4x-25/4
