Which equation is equivalent to x + 3y – z = 3?

3x + 6y – 3z = 6

4x + 12y – 4z = 12

2x + 4y – 2z = 8

2x + 3y – 4z = 12

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
