Me solve this step by step and answer within 20 minutes

y = 44

Step-by-step explanation:

Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.

So let us put this in a equation,

y = kx

where 'k' is constant

so k = y/x

let us put the figures of x and y from given first statement;

x = 7 and y = 18

so, k = 18 / 7

which means, k = 2.57

lets put this value of k in the equation above,

we know from statement that, x = 17 and k = 2.57

so, y = 2.57 (17)

which means, y = 43.71

or we can round it off to, y = 44

answer: the answer is 23

step-by-step explanation:

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
