Answer:
6
Step-by-step explanation:
since;
1/3 of 12 = 4
so,
(2/3) of x = 4
x=4(3/2)= 6
Minus 9, add 13, add 6, mus 9, add 13, add 6, minus 9 is next
34-9=25
the blank is 25
you don't list any expressions to choose from but
if width = x
and length = 2x
Area = 2x * x
Area = 2x^2
The correct option as per me is (b)
