Answer:
B.) transitive property of equality
Step-by-step explanation:
x = –3 and –3 = z, then x = z.
Symmetric property of equality: if a = b then b = a
Transitive property of equality: if a = b and b = c, then a = c
Closure property of multiplication: the set is closed under multiplication
Closure property of addition: the set is closed under addition

Answer: First option 3/10
Solution
The scale factor of dilation of triangle DEF is the ratio between the corresponding sides of the triangle D'E'F' and the triangle DEF:
Scale factor: f=D'F'/DF=D'E'/DE=E'F'/EF (1)
We can find the ratio D'F'/DF using the similar triangles OD'F' and ODF, because their sides must be proportionals:
D'F'/DF=OF'/OF=OD'/OD (2)
We know according with the figure:
OF'=3 and F'F=7, then:
OF=OF'+F'F→OF=3+7→OF=10
Then replacing in (2):
(2) D'F'/DF=3/10=OD'/OD
And replacing in (1):
(1) f=3/10=D'E'/DE=E'F'/EF
Answer: The scale factor of dilation of triangle DEF is 3/10
