Answer:
20
Step-by-step explanation:
20 x 2 =40
40 is under 58 and the closest to 58
the next 10 is 30 and 30 x 30 is over 58 with 60
Answer:
The correct option is B.
Step-by-step explanation:
It is given that triangle A"B"C" is the image of triangle ABC after transformation.
From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.
It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is

The corresponding sides of image A"B"C" are smaller than the preimage ABC.

Since k<0, therefore the transformation shows the reduction. The dilation rule is




Option B is correct.
Indirect proof or contradiction
Are there choices to pick from?
C is same thing as 1c
1c + 1/4c
(In simple words: Adding a whole to 1/4.)
1 + 1/4 = 1 1/4 or 5/4
same thing when having c:
1c + 1/4c = 1 1/4c or 5/4 c
Answer: 1 1/4c or 5/4c
