Answer:
Step-by-step explanation:
Answer: Choice A) Rectangle B'C'D'E' is larger because scale factor is greater than 1.
Going from (x,y) to (3x,3y) means we multiply each coordinate by 3. This is the scale factor. The scale factor being larger than 1 means the new image is an enlargement compared to the original preimage. Specifically the dimensions of the new rectangle are 3 times larger.
Answer:
1/25
Step-by-step explanation:
square has 4 sides, if you add them all up you get 4/5.
1/5+1/5+1/5+1/5=4/5
so each side is 1/5
Area=length * width
A=1/5*1/5=1/25
Are there choices to the answer or must you draw the graph?
