b

Step-by-step explanation:

C

Step-by-step explanation:

First, examine the information given

Snap is 12 FEWER than 3 TIMES the number of posts on insta, so:

s = 3i -12

Snap and insta COMBINED is 256 posts, so:

s + i = 256

So what we got now is:

s = 3i - 12

s + i = 256

Unfortunately, this is not one of the answers, but that's okay.

If you look at C, it says s = 256 - i. This is equivalent to s + i = 256.

So the answer is C

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
