If the shape on the red image is scaled to the shape on the blue image, the scale factor is 0.2777.
Explanation:
- The original shape's base in the red image is measured. The base of the red image is measured to be 9 units. Now we measure the same side of the blue image. The base of the blue image is measured to be 2.5 units. So after scaling, the length of the painting will be 2.5 units.
- To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the base of both images. So The scale factor =
=
= 0.2777. - So the red image is dilated by a scale factor of 0.2777 to produce the blue image.
Is there more information i can get out of this ?
Answer:
a believe it is c..........
So, parallel lines have the same slope, therefore a parallel line to 2x+12, will have the same slope as that one, so which is it?

so, we're really looking for the equation of a line whose slope is 2, and runs through -1,1.
Answer:
DE is parallel to AB, ∠ACB =∠DCE. So from symmetry of triangle. Δ DCE and Δ ABC are symmetric
