x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3

Answer:
6
Step-by-step explanation:
Maybe you have ...
f(x) = √(3x)
g(x) = x-6
Then ...
f(g(x)) = √(3(x -6))
The square root function is only defined for non-negative arguments, so we require ...
3(x -6) ≥ 0
x -6 ≥ 0 . . . . . divide by 3
x ≥ 6 . . . . . . . . add 6
The smallest number in the domain of f(g(x)) is x = 6.

Step-by-step explanation:
3.14(rs + r2)
3.14 (r= 2 x s= 3 + r =2 x 2)
3.14 ( 6+4)
3.14 (10)
3.14 x 10 = 31.4 units ² I guess
