Square rstu dilates by a factor of 1\2 with respect to the origin to create square r's't'u'. if r's' is 2 units, what is rs? a. 4 units b. 2 units c. 0.5 units d. 1 unit reset next

A.4 units

Step-by-step explanation:

We know that if a figure is dilated by a scale factor of k , then the measure of the corresponding image (l') of a line segment having measure 'l' is given by :-

Given : Square RSTU dilates by a factor of 1\2 with respect to the origin to create square R'S'T'U'.

The measure of line segment R'S' = 2 units

The scale factor :

Using the above equation , we have

Hence, RS = 4 units.

answer: x

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
