The third one pls mark me brainliest
Answer:
HN congruent to NL
Step-by-step explanation:
They have a line crossing both of them, signifiying congruence.
It would be 1n - 12 + 8y.
4n - 3n = 1n
12 + 8y don’t mix so we can leave it.
Therefore: 1n - 12 + 8y
C2+ 10
Twice = multiply by two
10 more than = add ten
Hope this helps!
