It can be simplified to: 14d+19e
It is an expression that can be simplified to: 12-5d
To simplify 8d -5 +7d -9d, combine the numbers with the ds and don't forget the -5. 8d + 7d - 9d = 6d Simplified, it is 6d - 5.
10d - 6 = 4d - 15 - 3d10d - 6 = d - 159d = -9d=-1

(c - 3d - 2)(c - 3d + 2)
(d - 8)(d - 1)
It can be simplified to: 14d+19e
3(25a^2 + 9d^2)
9d+3
It is an expression that can be simplified to: 12-5d
To simplify 8d -5 +7d -9d, combine the numbers with the ds and don't forget the -5. 8d + 7d - 9d = 6d Simplified, it is 6d - 5.
9d-19=6d+2 ... add 19 to both sides and subtract 6d from both sides... 9d-6d=2+19 3d=21 d=21/3 d=7
Seven, though they can be reduced to 3 if like terms are combined.
(-70-2+9)d + (39-75+1) = -63d -35
-7d = 50 + 2d -9d = 50 d = -50/9 Or about -5.6
