Step-by-step explanation:

So if you pick up 5 cards, all with a value of -7, that's :

-7, -7, -7, -7, -7

There's 5 "-7" cards, so it's 5 × -7

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
