<u>Answer:
</u>
f(x) = 3(x+2)(x-2)
<u>Step-by-step explanation:
</u>
We are given the following the quadratic function and we are to rewrite it in intercept or factored form:
 
We can factorize the given function so taking the common factors out of it to get:
 
 
The term  is in the form
 is in the form  so it can further be factorized to give:
 so it can further be factorized to give:
 
Therefore, the factored form of the given quadratic function is f(x) = 3(x+2)(x-2).
 
        
                    
             
        
        
        
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
        
                    
             
        
        
        
Answer:
135
Step-by-step explanation:
15/100 × 900 = 15 × 9 = 135
 
        
                    
             
        
        
        
P = 5 .............................................
this is how= 
first you expand the second equation 
<span>25 + 4p = -18 + -12 + 6p + 9p
</span>
then you add the like terms in the second equation:
25 + 4p = -30 + 15p
then this is how=
25+30 = 15p -4p
55=11p
p= 5
        
             
        
        
        
Answer:
Step-by-step explanation:
With regards to the factor 'walking device used', the ANOVA conducted on the cadence data revealed a main effect of walking device, and also with the results of the experiment giving rise to a p - value less than 0.05, we can reject the null hypothesis which says, there is no effect of the walking device factor.
We can thus conclude that there is not enough statistics evidence to prove that there is no interaction between the two factors or that there is no effect of the walking device given the cadence data.
