Answer:
11^9
Step-by-step explanation:
If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2
Because the two labelled line segments are parallel, it follows that the two triangles are similar and corresponding sides occur in the same ratio with one another.
In particular, this means
