Answer:
c 1/2
Step-by-step explanation:
You are incorrect.
We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.
Look at point (6, 0) which becomes (3, 0) in the dilation.
The distance from the origin to (6, 0) is 6 units.
The distance from the origin to (3, 0) is 3 units.
scale factor = dilated/original = 3/6 = 1/2
The scale factor of the dilation is 1/2.
Also look at segment AB whose length is 4. The length of segment A'B' is 2.
scale factor = dilated/original = 2/4 = 1/2
Answer: 1/2
Answer:
98.01
Step-by-step explanation:
Answer:
1. 5
2. 4
3. 20
4. 10
Step-by-step explanation:
You count the units of the length and width of the triangle which is also the same for the rectangle and l*w=the area (length is the longer side).
Halve the area of the rectangle to find the area of the triangle.
X + 2 = 10
X - 4 = 10
3x = 24
X/8 = 1
Those 4 are the correct answers
