Okay so, I am assuming the model is smaller so it would be 0.34m long.
The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200
Assuming the model is bigger (just in case) it would be 13,600m long.
The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600
Hope this helps
Answer:

Step-by-step explanation:
For surface area all you have to do is multiply each number by one of the other numbers x2.

There ya go
So, parallel lines have the same slope, therefore a parallel line to 2x+12, will have the same slope as that one, so which is it?
so, we're really looking for the equation of a line whose slope is 2, and runs through -1,1.
