Consider the transformations of a rectangle ABCD to produce a rectangle DEFG. Which sequence of Transformations results in rectangles that are similar but not congruent​

A.

Step-by-step explanation:

Rotations preserve shape and size, but a dilation with a factor of 3, no matter where in the sequence of transformations it is, results in a shape 3 times larger.  So rotation followed by the dilation will end up being a rectangle similar to the original but 3 times its size.

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
