Step-by-step explanation:
We have the following expression:
Factoring in the numerator:
Factoring again in the numerator with common factor 
:
Simplifying:
Hence, the correct option is C. x-2
Answer:
See below
Step-by-step explanation:
The starting point of 0 has a value of 3. The common difference of 2 is added at each step increse in n.
n f(n)
0 3
1 5
2 7
3 9
4 11
The can be modeled by the equation y = 2x+3
Your problem statement needs a bit of correction:
"<span>Y= -16t^2 +400, where t represents the number OF SECONDS after the camera is dropped. How long will it BE before Kay sees the splash from the camera hitting the water?"
Set y = -16t^2 + 400 = 0. We assume that 400 and 0 represent feet (English system).
Then 16t^2 = 400, and so 25 = t^2. Only the positive square root makes sense here, and that root is 5 (seconds).</span>
