I guess the only way to use subtraction is to take the total area of the grid and subtract it by the total area around the figure. So it since it is a 10 by 10 grid, it would be 100 (since 10*10=100) minus the area around the shape.
Answer:
I think it is 1
Step-by-step explanation:
10% of 500 is 50
then you multipy by 50 which is 1
I hope this helps;)
Answer:
B. Reflect PQR across a horizontal line through R, and then translate the image so R aligns with Z.
Step-by-step explanation:
Imagine a horizontal line through point R. Once you reflect the triangle across this line, it will be facing the same direction as triangle XYZ. Then, once you align R with Z (they are corresponding points!) the triangles will be directly on top of each other.
5 to be honest I just guess
