FAST I NEED THE ANSWER Which net can be folded to form a pyramid? A net has a square at the center. Squares are on 2 sides and triangles are on 2 sides. A net has a square at the center. 2 triangles are on 1 side, and 2 triangles are on another side. A net has a square at the center. 3 triangles are on 1 side. A net has a square at the center. A triangle and square are on 1 side and a square and triangle are on another side.
Eeehh like I think it's the right answer that is the right on
Refer to the picture I've attached.
As far as I know a pyramid net has a square in the centre and 4 triangles, each joining an edge of the square.
Hope this makes sense and helps. :)
hello from mrbilldoesmath!
2. 240 ( sqrt(1/12) + x ) (sqrt(1/12) - x)
12x - 3x^2 = => factor x from each term
20 - 240x^2 = => factor 240 from each term
240 ( 20/240 - x^2)= => 20/240 = 2/24 = 1/12
240 ( 1/12 - x^2) = => as a^2 - b^2 = (a+b)(a-b)
240 ( sqrt(1/12) + x ) (sqrt(1/12) - x)
