A = h ( x + 10 ) 2 A = 27 h = 4 Work out the value of x .

A=h(x+10)/2

a=27

h=4

24×2=4(x+10)

54÷4=x+10

4x=54-40

4x=14

x=7/2

x=3.5

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
