Answer:

Yes, because both figures are rectangles and all rectangles are similar (B)

Question:

The complete question related to this found at brainly (question Id: 2996738) is stated below:

Is rectangle EFGH the result of a dilation of rectangle ABCD with a center of dilation at the origin? Why or why not?

a. Yes, because corresponding sides are parallel and have lengths in the ratio 1/4

b. Yes, because both figures are rectangles and all rectangles are similar.

c. No, because the center of dilation is not at (0, 0).

d. No, because corresponding sides have different slopes

Step-by-step explanation:

Coordinates of rectangle EFGH

E (-4,4), F(4,4), G(-4,0), H (4,0)

EF = 8

FG =4

GH= 8

HE= 4

Coordinates of rectangle ABCD

A (-3,3), B(3,3), C(-3,0), D (3,0)

AB = 6

BC = 3

CD = 6

DA = 3

Find attached the diagram.

Image = EFGH, pre-image = ABCD

Scale factor = (sides of the image)/(sides of the pre-image)

= 8/6 = 4/3

Similar shapes have same shapes but different sizes. From the result obtained, the two shapes are similar with different sizes.

Rectangle EFGH is the result of a dilation of rectangle ABCD with a center of dilation at the origin.

Reason: the lines connecting the coordinates of both shapes meet at the origin. And also both figures are rectangles and all rectangles are similar (B)

I don't know how to do this<br> Y=x-7<br> 3x-3y=21
lora16 [44]
You're going to use the substitution method for this.

First, we know that Y = x-7, so we can plug x-7 into everywhere we see Y!

3x - 3(x - 7) = 21

then we simplify

3x - 3x + 21 = 21
^      ^
These cancel out!
So we're left with...

21 = 21

That means that the solution to this equation is all real numbers!

I already give you the answer for number 19 but can you please explain. And then can you tell me what question number 20 is and
madreJ [45]
So, You know the outer angle, so you need to know the inner angle on <B. so 180-148 is 32. since you know two of the inside angles, and all triangle angles add up to 180 degrees, take 32+83, which is 115, and subtract that from 180, which is 65
Hope this helps!
