Samuel and Jackson are brothers. Samuel is three years older than twice the age of Jackson. If the sum of their ages is 18, how old are the brothers?

Samuel = 13yrs

Jackson = 5yrs

Step-by-step explanation:

Samuel = 2x + 3

Jackson = x

sum = 18

2x + 3 + x = 18

3x = 18 - 3

3x = 15

x= 5yrs

Samuel = 2x + 3

             = 10 + 3

             = 13 yrs

Jackson = x

             = 5yrs

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
