12 times 34 is 408. Hope that helped.
4.2.
If the 2 inch side was scaled to 10.5 inches the 5 inch side would be scaled by 10.5/2 = 5.25, so would be 25.125 inches which is too big.
So the 10.5 inches is the 5 inch side on the original, and so it 10.5/5 = 2.1 times bigger.
Therefore the smaller side would be 2*2.1/= 4.2 inches.
It should be 5>=
Your welcome
Answer:

Step-by-step explanation:
Honestly not sure what all the numbers you put down were (numbers for the graph?), but here is how to find the slope :)
First, find two "exact" points!
I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is 
(I hope this helps, have a nice day!)
