Answer:
B 3x+2 
Step-by-step explanation:
perimiter=2L+2W
P=2(L+W)
if x=width then
P=2(L+x)
P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4
B is answer

Answer:

And we can find this probability using the normal standard distribution and we got:

Step-by-step explanation:
For this case we have the foolowing parameters given:
 represent the mean
 represent the mean
 represent the standard deviation
 represent the standard deviation
 the sample size selected
 the sample size selected
And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:

And we want to find this probability:

We can use the z score formula given by:

And we can find this probability using the normal standard distribution and we got:

 
        
             
        
        
        
For a ratio make a fraction using the quantities of the colors.
 You want the ratio of red to purple.
 There are 16 red and 2 purple, so the ratio would be 16/2, which can be reduced to 8/1
