Answer:
C.
Step-by-step explanation:
3(2x + 1)=6x + 3
3*2x=6x, 3*1 = 3
so therefore 3(2x+1)=6x + 3
Given the movement of Dolphin has been modeled by the function:
h(t)=-16t^2+26t
the time taken for Dolphin to reach 5 feet will be:
5=-16t^2+26t
writing the above in quadratic form ax^2+bx+c=0 we get:
16t^2-26t+5=0
solving the quadratic equation using quadratic formula we obtain:
t=13/16+/-√89/16
t=0.22 sec or 1.40 sec
The factors of the equation 
will be 
<h3>What will be the factors of the given equation?</h3>
When we split the equation into two groups we will get
Now taking (x-1) common
Thus the factors of the equation will be
