Answer:
its 18
Step-by-step explanation:
Answer:
40x30= 1200, 20x15=300, 300/1200= 1/4.
Step-by-step explanation:
You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.
Answer:
W'' = (2, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate.
So, point W' is (-2, -3).
Reflection over the y-axis changes the sign of the x-coordinate.
So, point W'' is (2, -3).
___
The answer can be determined by doing the reflections algebraically, as above, or by doing them on a graph, as below.
