Tiffany sees this given dilation and claims that the scale factor is 2
Alenkinab [10]

Answer:

The scale factor is not 2

Step-by-step explanation:

Given

See attachment for the dilated triangles

Triangle ABC is dilated through center point O to form triangle A'B'C'.

From the attachment, we have:

OC = 2 i.e. the distance from the center point to C

and

OC' = 6 i.e. the distance from the center point to C'

The length of OC' is calculated using:

OC' = OC + CC'

OC' = 2 + 4

OC' = 6

The scale factor (k) is then calculated by dividing OC' by OC

k = \frac{OC'}{OC}

k = \frac{6}{2}

k = 3

Hence, Tiffany's claim is incorrect.

oksian1 [2.3K]

Answer:

a) 4 cm

b) 5 cm

c) 10 cm

Step-by-step explanation:

The side lengths of the reflected square are equal to the original, and the distance from the axis(2) also remains the same.  From there, it is just addition.

Hope it helps <3

The measure of a side of a square is x units. A new square is formed with each side 6 units longer than the original squares sid
aliya0001 [1]
To answer this, you will represent the new side length of the square as x + 6.

To find the area you will multiply (x + 6) by (x + 6).

To do this, you will multiply x and x, x by 6 twice and 6 by 6.

See the attached picture for the expression representing the area of the new square.
