Infinitely many, because x can be anything and the equation will still be valid
Answer: 90 hawks counted were not red tail.
Step-by-step explanation: If there were 30 hawks to count for a fourth of the hawks counted to solve you just must include the other 3 counting of 30 hawks resulting within the of the full 120 hawks counted only 30 were red tail.
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in

<span>Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2

I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
Answer:
m=21 and n=21
Step-by-step explanation:
In order to maximize the area of the rectangle, you want the two side lengths to be as equal to each other as possible.
In this case, we get that 2m+2n=84, so m+n=42. In our case, m and n can equal each other, so that gives us the maximum area of 441
Proof that this works:
If we had other dimensions, like m=20 and n=22, the area would be 440, slightly less than 442. If m=19 and n=23, the area becomes 437, which is even further off from 441.
