Iwill be giving 15 points to whomever answers !

which confirms that rectangle abcd and rectangle efgh are similar after the similarity transformation of a rotation followed by a dilation?

a)
ad/gh= cd/eh= bc/ef= ab/fg= 4
b)
ad/gh= cd/eh= bc/ef= ab/fg= 2
c)
ad/eh= cd/gh= bc/fg= ab/ef= 2
d)
ad/eh= cd/gh= bc/fg= ab/ef= 1/2

C)  

AD/EH= CD/GH= BC/FG= AB/EF = 2

Step-by-step explanation:

Rectangle ABCD and rectangle EFGH are similar

So

AD/EH = 4/2 = 2

CD/GH =8/4 = 2

BC/FG = 4/2 = 2

AB/EF = 8/4 = 2

So

AD/EH = CD/GH = BC/FG = AB/EF = 2

To find if the rectangles are similar divide the side of the larger one by the corresponding side of the smaller one and see if the ratio of each side matches:

C)  AD/EH= CD/GH= BC/FG= AB/EF= 2

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
