Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees, so no.
Answer:
Perimeter = (lenght×2) + (width×2)
Perimeter = (2.5n×2) + (2×(4n+5))
Perimeter = 5n + 8n + 10
Perimeter = 13n + 10

Use distributive prpoerty
a(b+c)=ab+ac
distribute each
3k(-5k+21)=-15k^2+63k
2(2.5k+90)=5k+180
so nowe we have
-15k^2+63k+5k+180
add like terms
-15k^2+68k+180
that is the answer
