Which is the correct algebraic expression after combining like terms?

6cd+3c-7d-3cd+4d+1/3c

a) 3cd+2 2/3c-11d

b) 3cd+3 1/3c-3d

c) 9cd+2 2/3c-3d

d) 9cd+3 1/3c-3d

  b)  3cd+3 1/3c-3d

Step-by-step explanation:

It can work well to factor the variables out so you can see the coefficients more easily:

  6cd+3c-7d-3cd+4d+1/3c

  = (6 -3)cd +(3 +1/3)c +(-7 +4)d

  = 3cd +(3 1/3)c -3d

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the equivalent expression are always the hardest ones but you look at the gcf also
