The difference of a number and seven is x - 7. So twice that, would be:
2(x - 7)
 
        
             
        
        
        
OK so my answer is from what you’ve just explained that means you multiply the six and the 114 is 684 so that means if you have to do that to 13 of them that means 684×13 is what your equation would be in the answer to 684×13 is 8892
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
<u>Ratio of corresponding sides:</u>
- CD/BC = BC/AB
- CD/6 = 6/9.6
- CD = 6*6/9.6
- CD = 3.75 cm
Correct choice is C

Answer:
   a. 1.48 seconds
Step-by-step explanation:
You want to find the larger value of t such that h(t) = 10.
   -16t^2 +25t +8 = 10
   16t^2 -25t +2 = 0 . . . . subtract the left side to get standard form
Using the quadratic formula, we find the values of t to be ...
   t = (-(-25) ± √((-25)^2 -4(16)(2)))/(2(16)) = (25±√497)/32
   t ≈ 0.08 or 1.48
The ball goes in the hoop about 1.48 seconds after it is thrown.

<em>Additional comment</em>
The quadratic formula tells us the solution to ...
   ax² +bx +c = 0
is given by ...
   
Here, we have a=16, b=-25, c=2. Of course, our variable is t, not x, but the relation is the same.
