Answer:
2 x^4
Step-by-step explanation:
Recall that the GCF is the greatest of the product of factors that are common to all these three expressions
then for the pure numerical part, the factor common to 50, -10 , and 2 is "2"
and for the variable part x^4 is the largest common to all three expressions.
Therefore the GCF is: 2 x^4
 
        
                    
             
        
        
        
I think c .. I already took a course .. and the test had that question.. I cant remember the answer though
        
                    
             
        
        
        
Answer:
144π
Step-by-step explanation:
we need the radisu
circumference formula: 2πr
2πr=24π
12=r
area formula:
πr²
12²π= 144π
 
        
             
        
        
        
There are 2 answers: Choice 1, Choice 4
=======================================
Why is this? Because we use the rule 
P(A & B) = P(A) * P(B)
which only works if events A and B are independent
----
For the first answer choice, 
P(A) * P(B) = 0.6*0.4 = 0.24 = P(A & B)
so that matches. 
The same applies to the fourth answer choice as well
P(A) * P(B) = 0.3*0.2= 0.06 = P(A & B)
----
The other answer choices don't match up. 
The second answer choice has
P(A) * P(B) = 0.3*0.4 = 0.12 but that doesn't match with the 0.70 given
Similarly for the third answer choice,
P(A) * P(B) = 0.5*0.1 = 0.05 which doesn't match with the 0.60
