Answer:
Part A: 6r + 5
Part B: r = 9
The rectangle measures 20 inches by 59 inches
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.
