The answer is 36 positive
Answer:Parts of two triangles can be proportional; if two triangles are known to be similar then the perimeters are proportional to the measures of corresponding sides. Continuing, if two triangles are known to be similar then the measures of the corresponding altitudes are proportional to the corresponding sides.

1. -9 need to multiple to both number
-9 X n= -9n -9 X -3 = 21
-9n + 21
2. -10 X 9n = -90n -10 X 3 = -30
-90n - 30 - 8
-90n - 38
