7/12*6/14
  7*6=42
  12*14=168
=42/168
=0.25 =1/4
        
             
        
        
        
Answer: (2x+5)(2x−5)
Step-by-step explanation:For me, what i like to do is to try divide the problem into two parts. For example in this problem, you would divide the 4x^2 into two 4x(since 4x+4x = 4x^2). Then 25 can be divide into into 5s (5x5=25). SInce you know that its a negative 25, you know that it has to be a negative on one of the sides. So the answer in factor form is (2x+5)(2x−5)

the radius: r^2 = 81
r =9
c = 2*pi*r
  = 2 * pi * 9
  = 18 *pi
 Answer: 18*pi or approximately 56.62
