x-3 and x+5 we can't do anything with so next 
5(x-3)=5x-15
2(x+5)=2x+10
5x-15+2=5x-13
(2x+10-9)=2x+1
(5x-13)-3(2x+1)
-3(2x+1)=-6x-3
5x-13-6x-3=-x-16
4(-x-16)=-4x-64
the answer is -4x-64
        
                    
             
        
        
        
Yes it is true that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars because null hypothesis is rejected.
Given among 2049 Connecticut passenger cars, 239 had only rear license plates. Among 334 Connecticut trucks, 45 had only rear license plates.
let  be the probability that commercial cars have rear license plates and
 be the probability that commercial cars have rear license plates and  be the probability that connected trucks have rear license plates.

Test statistic Z=p difference/standard error
=(0.1166-0.1347)/0.0066
=-0.0181/0.0061

p value=0.001505<5%
Since p is less than 5% we reject null hypothesis.
We cannot calculate standard deviation so  we cannot calculate confidence interval.
Hence there is statistical evidence at 5% significance level to support that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars.

Answer:
The Factor of expression using the greatest common factor is 
Step-by-step explanation:
Consider the provide expression.

We need to Factor the expression using the greatest common factor.
First look at the coefficients of the variable.
The coefficients are the factor of 2.
Variable p is the greatest common factor in the provided expression.


Hence, the Factor of expression using the greatest common factor is  .

Answer:
Nick needs to buy 3 packs.
Step-by-step explanation:
If Nick buys 3 packs he will have 18 cards. If he uses 15 of them he will have 3 left over. If he only bought 2 packs he would be 3 cards short of the amount he really needed.
