Let us say that:
a = black kittens
b = white kittens
We know that:
a = 5 b
a + b = 25
Therefore:
5 b + b = 25
6 b = 25
b = 4.17
But we cannot have a fraction value for the number of
kittens, so round off:
b = 4
So a is:
a = 25 – 4 = 21

Answer:
16m^2 + 72m + 81
Step-by-step explanation:
you expand it, by (9+4m)(9+4m), using distributive property you get
81 + 36m + 36m + 16m^2, simplifying you get the answer
complementary angles are angles that, when added together, make 90 degrees.
