18.5-0.5= 18
18/3= 6
So r=6
350*15 is 5250. That is the total words needed to reach her assignment paper goal. Since there are 60 minutes in an hour we would need to figure out how many words she can type per hour. 60*70 is 4200. Then we divide 5250 by 4200. We get 1.25. Soooo our final answer would be 1 hour and 15 minutes need to be set aside to type her assignment. I really hope this is correct it makes sense to me. If not i am truly sorry.

Answer:
3 inches by 12 inches
Step-by-step explanation:
Length = L
Width = W
LW = 36
L = 36/W
2(L + W) = 30
2(36/W + W) = 30
36/W + W = 15
36 + W² = 15W
W² - 15W + 36 = 0
(W - 3) (W - 12) = 0
W = 3 or W = 12
Therefore the dimension is 3 inches and 12 inches.
