You would need to shade 1.5 boxes or 6 pieces to have shaded 25% of the shape.
In total, there are 6 boxes. There are 4 pieces per box. In total, there are 24 pieces.
6/4 = 1.5
24/4 = 6
You would need to shade 1.5 boxes, which is equal to 6 pieces or triangles.
Hello!

A proportion that can be used to represent the picture sizes is p(poster printed) times 4 equals e(enlarged poster), or p*4=e.

Have a great day!
So over 4 years, this computer's value will go from 4,500 to 700.
That's a difference of 3,800 over 4 years. Straight-line means the amount is the same every year, so

= 950
So the depreciation expense each year is 950.
To get the area of the shaded region, we must subtract the area of the bigger triangle on the outside and the area of the smaller triangle inside the bigger triangle.
Set up the equation:
Area of big triangle - Area of small triangle = 

So the area of the shaded region is 96.
Hope that helps!
Area equals the bbhffc and I don't think that I have a great answer
