You can identify similar polygon by comparing their corresponding angles and sides. ( if they are the same the ratio of the lengths is the scale factor. Also check if their sides are proportional.)
Answer: 10
How?
2/5= 4 tiles
1/10= 1 tile
1/2= 5 tiles
Add them up and there is your answer.
All you would have to do is add the two numbers together if im interpreting the question right so it would be 415 miles
Distribute
3(x+3) = -2(2x-1)
3x+9 = -4x+2
Collect like terms
3x+4x = 2-9
7x = -7
x = -1
96+80= (100-4)+(100-20)
= 200-24
=174
