Don't go any further. There is nothing else to do. These are unlike terms and cannot be reduced or combined.
I think that 3 rolls is wrong and that 6 rolls is right. If you create a 15 by 15 square and draw two lines through the center that connect to the opposite corner, you'll be able to use the Pythagorean Theorem.
Perimeter: 15+15+15+15=60ft.
Length of Line from Corner to Corner:
(15)(15)+(15)(15)=C^2
225+225=C^2
450=C^2
21.2=C
21.2(2)= 42.4ft.
42.4ft.+60ft.= 102.4ft.
102.4ft. divided by 20ft. = 5.12 = <u>6 rolls</u>
Answer:
from looking a the table we can see that hours is 4 and dollars is 72 so we divide 72/4=18 so one hour is 18 or on the graph
18,1
then we divide 162 by 18=9 on the graph
162,9
watch out this graph is by tens not ones
