Shivani has two pieces of wire, one 48 feet long and the other 21 feet long. If she wants to cut them up to produce many pieces of wire that are all of the same length, with no wire left over, what is the greatest length, in feet, that she can make them?

3 feet

Step-by-step explanation:

48 = 2⁴×3

21 = 3×7

Greatest common factor of 48 and 21 is 3.

Each piece will be 3 feet long.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
