Answer:
B 1.8
Step-by-step explanation:
Answer: A' (5,9)
Step-by-step explanation:
1. You have that the translation is 
⇒
and the coordinates of A is (-2,5). Then:
⇒
2. As you can see, -5 is 7 units below of the line of reflection 
, therefore, you can know the coordinates of A' as following:
3. Then, the coordinates of A' is (5,9)
Answer:
The length of the yard is 102
Step-by-step explanation:
If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.
The answer is D that is (18+41)+12 = 18+(41+12)
because A,B,C can be only be associative when
(A+B)+C= A+(B+C)
So by comparing the associative law with the options above , you will be able to get your answer
