D + 3D = 240
4D = 240
Divide both sides of the equation by 4: D = 60

∙ 13y ago1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8
c = 6 and d = 7
So you basically have, (27D-9)+3D = 29+(27D+1) 30D-9 = 27D+30 3D = 39 D = 13
They can be simplified to 10d
If your talking maths then its 4 d if your talking viewing on a a screen 3d is 3 dimension and d is dimension
1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8
c = 6 and d = 7
5d+3d = 15 8d = 15 d = 15/8 = 1.875
So you basically have, (27D-9)+3D = 29+(27D+1) 30D-9 = 27D+30 3D = 39 D = 13
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
8d = 5d+18 8d-5d = 18 3d = 18 d = 6
the answer is a
it would be 1 fourth multiplied by quanity d squared plus 3d plus 9 (1/4)(d2 + 3d + 4)
They can be simplified to 10d
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
They are: 6d+6 or 6(d+1)
If your talking maths then its 4 d if your talking viewing on a a screen 3d is 3 dimension and d is dimension
