No
Step-by-step explanation:
Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.

Answer:
FD = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
= 
( cross- multiply )
2(2x + 2) = 3(x + 3) ← distribute parenthesis on both sides
4x + 4 = 3x + 9 ( subtract 3x from both sides )
x + 4 = 9 ( subtract 4 from both sides )
x = 5
Thus
FD = x + 3 = 5 + 3 = 8
