Answer:
4X + 5
Step-by-step explanation:
We start with the unknown number, X.
Doubling the number :
⇒ 2 × X
⇒ <u>2X</u>
<u />
Adding 5 to double the number :
⇒ 2(2X) + 5
⇒ 4X + 5
First, distribute the 2.
2x+6=6+2x
These are the same, so therefore it is infinitely many, because whatever you plug in for x will work.
Answer: The second one which is x > 15
The scale factor is some number between 0 and 1 (not including either endpoint) because the image is smaller than the preimage.
Triangle ABC is the preimage, or the "before"; while triangle A'B'C' is the image, which is the "after".
preimage ----> image
before ----> after
