Answer:
1. (-2,-7)
2. (3,-9)
3. (7,-2)
4.(-3,9)
Step-by-step explanation:
Since the reflection is across the x-axis, the y-coordinate will be flipped.
Example: (-7,4) would become (-7,-4)
HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.
Example: (-7,4) would become (7,4)
Always true
Perimeter: 64 cm
21 + 21 = 42 cm 11 + 11 = 22 cm
42 + 22 = 64 cm
i say A because you cant add W with 12 nor 16 and its not D because the W needs to be squared
