Step-by-step explanation:
Hope it helps.
5 per sample
8 samples
5 x 8 = 40 black bears
The answer is 7.46 , so when rounded, the answer is B
90 + 20x + 10x = 180
30x = 90
x = 3
The answer is the last option (Option D), which is:
D. 25
The explanation is shown below:
1. You have that:
(a ± b)^2=a^2 <span>± 2ab + b^2
2. The expression given in the problem is:
</span><span>x^2-10x+n
Where x^2=a and 2ab=10x
2b=10
b=10/2
b=5
3. Therefore, you have:
b^2=5
b^2=25
b^2=n
n=25</span>
