The answer is D. All you have to do is graph the equation, and you will have the vertex and the roots. By the way, you can rule out B and C because those two do not follow the rules of a quadratic. Also, A and B have the wrong axis of symmetry, because the rocket lands after 10 seconds.
So the pattern is x,y so the left is x and the right is y. Just graph it
Answer:
-28
Step-by-step explanation:
If the long side on both is 9ft and 3ft then 3•3 is 9 so for the short side you do the same. If the short side is 1ft and the other is "j" then it's 1•3 is 3.
1•3=3
Sorry if it's confusing the way I explained it.
