Rectangle wxyz was dilated using the rule rectangle w x y z is dilated to form rectangle w prime x prime y prime z prime. the length of w x is 5 and the length of x y is 4.. d subscript z, twelve-fifths what is w'x'? 8 units 10 units 12 units 14 units

The dilation transformation forms an image that have lengths that are a

product of the lengths of the sides of the preimage and a scale factor.

Reasons:

Given parameters:

The Preimage of the dilation is rectangle WXYZ

The image formed after the dilation is W'X'Y'Z'

Required:

The measure of W'X'

Solution:

The probable rule for the dilation obtained from a similar question is

Therefore;

Which gives;

XY = 4

Therefore;

W'X' = 12 units

The length of W'X' will be exactly given by, 12 unit.

Step-by-step explanation:

Rectangle WXYZ is dialated by a factor of to form the rectangle W'X'Y'Z'.

So, if the length of WX is 5 unit, the length of W'X' will be exactly given by,

lenght of WX Dialation factor

=  unit

= 12 unit

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
