3/5 + 4/9 find the sum answer with supporting work.

answer:

first 3/5+4/9=27/45 by doing 5x9=45 then 3x9=27 next do 4x5=20/45

second add (only the numerators the top numbers) 27/45+20/45=47/45

third mixed numbers 47 can go into 45 1 time then the left over 2 will be the numerator so its 1 2/45

last add the -1 2/45

answer: -1 2/45 hope this

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
