4. is A 15
5. is C 12
6. is B 4, 8, 12, 16
hope this helps :)
This system of equations is consistent and independent, because there is only one solution. the answer is C
Answer:
14%, 1/4, 1.4
Step-by-step explanation:
14% = .14
1/4 = .25
1.4 = 1.4
Adds 4 each time and 5-4=1 so nth term is 4n + 1
Refer to the edited figure.
Triangles ABC and A'B'C' are similar because of AAA.
Also,

Therefore
ΔA'B'C' is 1/3 the size of ΔABC.
This means that the scale factor from ΔABC to ΔA'B'C' is a 3-factor reduction.
Answer: reduction; one-third.
The dilation is a reduction.
The scale factor of the dilation is one-third.
