4 times (x^2-9x+8). Hope that helps!
Answer:
Distance=520cm
Step-by-step explanation:
The solution is in the image
L = 2W
A = 50
A = L x W
50 = 2W x W
50 = 2W^2
W^2 = 25
W = 5
so L = 2W = 2(5) = 10
P = 2(L+W)
P = 2(10+5)
P = 2(15)
P = 30
answer
P = 30 in
The scale factor used to create the dilation is 3
You can easily find out by counting the sides
The coordinates of the pre-image are
(-2,-1) , (-2,1) , (-5,1)
the vertical line counts to 2 boxes
the horizontal line counts to 3 boxes
The coordinates of the image are
(4,-1) , (4,5) , (-5,5)
the vertical line counts to 6 boxes
the horizontal line counts to 9 boxes
![\frac{6}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B2%7D%20)
= 3
![\frac{9}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B3%7D%20)
= 3
The scale factor is 3
