rectangle abcd is rotated 180°. what rule shows the input and output of the rotation, and what is the new coordinate of a′?

(x, y) → (−x, −y); a′ is at (5, −1)
(x, y) → (−y, x); a′ is at (−1, −5)
(x, y) → (y, −x); a′ is at (1, 5)
(x, y) → (x, −y); a′ is at (−5, −1)

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

what is the information provided?

step-by-step explanation:

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
