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.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
