<span>Arc length = C*(21/360)
so the answer is D</span>
        
             
        
        
        
Answer:
Step-by-step explanation: It’s C thank me later
 
        
             
        
        
        
S=d/t
45=29/t
t=45/29
convert to min
t=45/29 *60=38.66min
        
             
        
        
        
The expression that is equivalent to 14xy – 28x – 36y + 48 is 2[7x(y-2)-6(3y-4)]
<h3>Factorizing expressions</h3>
Factorization is a way of separating the equations into two separate factors.
Given the expression below;
14xy – 28x – 36y + 48
Group
(14xy – 28x) – (36y + 48)
14x(y - 2) - 12(3y-4)
Factor out the value of 2 from both terms
2[7x(y-2)-6(3y-4)]
Hence the expression that is equivalent to 14xy – 28x – 36y + 48 is 2[7x(y-2)-6(3y-4)]
