<span>√x^2+2x-10=√x+20
raising both members to the square
</span> x^2+2x-10=x+20
rewriting
x^2+x-30=0
factoring
(x+6)(x-5)=0
therefore the solutions are
<span> x = –6, x = 5
</span>the answer is
<span>B. x = –6, x = 5</span>

Answer:
h(t) = - 16t² + 96t
Step-by-step explanation:
A soccer ball is kicked vertically from the ground with an initial velocity of 96 ft/sec.
So, it initial height,
ft. and initial velocity
feet/sec.
Now, the quadratic function, h(t), that shows the height, in feet, of the soccer ball, t seconds after it was kicked will be given by the general equation

⇒ h(t) = - 16t² + 96t + 0
⇒ h(t) = - 16t² + 96t (Answer)
