the 2d means 2 letter d and the 3d means 3 letter d . example: 2d= d d 3d= d d d
2d
3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
2 D
First you kiss then you kiss and touch then you have sex! :D
2D is two dimensions and 3D is three dimensions. 2D and 3D animation is animation that works in 2D and 3D. Often, 3D is used instead of 2D in order to enhance the perception of quality, even though the 3D is rendered on a 2D visual field. Its a matter of perspective. (Pun intended.)
It means 2d whereas 3d means three dimensional
It means that each number in the sequence is formed from the previous number by adding d to it. So, 1, 1+d, 1+2d, 1+3d, etc or 4, 4+d, 4+2d, 4+3d, etc
1 or d
3d + 8d - d - 5 = 10d - 5 = 5*(2d - 1)
3d-3d cancel 2d-3d=-1d 8=-1d-17 -17+17 cancel 8+17=25 25=-1d 25/-1=-1d/-1 d=-25
