Answer:

Part A: 6r + 5

Part B: r = 9

The rectangle measures 20 inches by 59 inches

Step-by-step explanation:

Part A:

(18r^(2)-27r-35)/3r-7

=6r + 5

Part B:

I just divided 1180 by the numbers on the list until I got an answer that was another number on the list. Then i took the greater number, 59, and set 6r + 5 equal to that like so:

6r + 5 = 59

6r = 54

r = 9

and i set 3r - 7 equal to the smaller number, 20:

3r - 7 = 20

3r = 27

r = 9

Hope this helps.
