It's 192, I'm pretty sure. I hope that you get this right! :^)
Answer:
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
Answer:
4
Step-by-step explanation:
Plug in -3 for x into the equation.
(1/4)^-3
And solve
(1/4)^-3 = 64
