Scott needs to replace a broken window at his house. The window is shaped like a triangle with
dimensions shown below. If glass costs $18.75 per square foot, how much with the replacement
window cost?

Step-by-step explanation:

Find the volume of the triangle and then multiply it by the unit cost for the glass:

Supposing the glass is in the shape of an equilateral triangle of side length s.  The height of the triangle is s*sin 60 degrees.  Thus, the area of the triangle is  A = (1/2)(base)(height) = (1/2)(s)(s*sin 60 degrees or approximately

A = (1/2)(s^2)(1/3)√3 square feet.  This simplifies to

A = (1/6)√3s^2 ft^2.

Then the glass cost is (1/6)(√3)s^2($18.75 per ft^2).

answer: it's a

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
