First, convert the 90 feet of the real plane to inches so that you can find the scale:
90 x 12 = 1080
Now, divide the inches of the real wing span by the inches of the model wing span:
1080/18
Now you want to simplify. The easiest way to start is dividing the top and bottom by 2:
540/9
Now try dividing the top and bottom by 9:
60/1
So your scale is 1 inch of model airplane to 60 inches of actual airplane.
Answer:
cd
Step-by-step explanation:
it's answer is 82 but I think
it will wrong
Answer:
x^3 + 3x^2 + 2x = x(x^2 + 3x + 2)
= x(x^2 + x + 2x + 2)
= x(x(x+1) + 2(x+1))
=x(x+1)(x+2)
Hope this helps!
