Figure D , the small rectangle, was dilated with the origin as the center of dilation to create Figure E , the large rectangle. Which rule best represents the dilation that was applied to Figure D to create Figure

(x,y) (3x, 3y)

Step-by-step explanation:

The side length of the small figure is 3 and the side length of the large figure is 9. And 3×3is 9.

See figure below

Step-by-step explanation:

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
