Starting for (0,0) count how many times you go up to the marked line (which is 2)

The [+] 2 is where you would start off at on the graph, with 1/2 being the slope go up one and over two.
There are 120 different possible groups.
(10 * 9 * 8)/(3 * 2 * 1) + 120
Answer:
A
Step-by-step explanation:

Answer: Length: 4, width: 6
Step-by-step explanation:
Let the length be x and width be y
Then x=2y-8 and xy=24
Substitute to get 2y-8 * y = 24, so 2y^2-8y=24 or y^2-4y=12, then solve to get y=6 or y=-2. Since width is positive y=6.
Substitute y=6 into xy=24 to get x=4.
Length: 4, width: 6
