It could be done by: (3*3)/(3*3) = 1
4=4(3s) 4=12s s= 1/3
3x7+4x2
(3*3+3)/3=4
4y - 4 + 3s + 7 - 6a - 4 = 0 4y + 3s + 7 - 6a - 4 = 4 4y + 3s - 6a - 4 = 4 -7 4y + 3s -6a = 4 - 7 + 4 4y + 3s - 6a = -3 + 4 4y + 3s - 6a = 1 y + 3s - 6a = 1/4 y = -3s + 6a + 1/4 3s = -y + 6a + 1/4 s = -1/3y + 6a + 1/4 -6a = -1/3y + a + 1/4 -a = -1/3y x 1/6 + a + 1/4 x 1/6 a = 1/18y - 1 - 1/24 a = 1/18y - 25/24
4 3s = 4*3 = 12, which is a rational number.
(2(4 + 1) - 3)
you can make a square based pyramid using 4 triangles and a 1 square
4
12 1/3s is 12/312/3 = 4
32 - 4 + 1 =29
