Answer:
3
Step-by-step explanation:
<u>1) Find two corresponding lengths between the image and the pre-image</u>
Pre-image (bottom side) = 3 units
Image (bottom side) = 9 units
We can use any corresponding lengths for this step.
<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>
9 units ÷ 3 units
= 3
Therefore, the scale factor of the dilation is 3.
I hope this helps!

Answer:
Step-by-step explanation:
x²-px-p-c=0
sum of roots=α+β=-b/a=p
product of roots=αβ=c/a=-p-c
(α+1)(β+1)=αβ+α+β+1=-p-c+p+1=-c+1
