Amswer:x= -41/20
Solutions:
(2x + 3)2 + 8(2x + 3) + 11 = 0
4x+6+16x+24+11=0
20x+41=0
20x=-41
x= -41/20
Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_

, where
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :


[Round to next integer.]
Hence, the required minimum sample size = 18
Let's say side length is s.
s*s = 500, so s = √500.
4 sides needed, total length thus 4*s.
4√500 ≈ 89.4
The total cost for peaches is $0.40 you get that by (0.5)(0.80) as for oranges (0.7)(.90)=$0.63 so $0.40+$0.63=$1.03
Divide one half by what
IF your talking about this
100 divided by 1/2 then it would be 50 and all i did was put the multiply 100 by .5
