<span>Answer:
(x + 4)/(x^2 - 3x - 10) * (x - 3)/(x^2 + x - 12)
= (x - 3)(x + 4) / (x + 2)(x - 5)(x + 4)(x - 3)
= 1/(x + 2)(x - 5)</span>
I think the answer will be A. but i dont know for sure.

Answer:
v(t2-t1) +d1= d2
Step-by-step explanation:
v = (d2-d1) / (t2-t1)
Multiply each side by (t2-t1)
v (t2-t1) = (d2-d1) / (t2-t1) * (t2-t1)
v(t2-t1) = d2-d1
Add d1 to each side
v(t2-t1) +d1= d2-d1+d1
v(t2-t1) +d1= d2
