Here is how to do the question,
The Remainder Theorem starts with an unnamed polynomial p(x), where "p(x)" just means "some polynomial p whose variable is x". ... If you get a remainder, you do the multiplication and then add the remainder back in. For instance, since 13 ÷ 5 = 2 R 3, then 13 = 5 × 2 + 3. This process works the same way with polynomials.
Hope that helps!!!!
Answer:
For only the rectangle (that I've coloured in with red) I assume it would be 9 inches squared. However, when adding on the triangles on the side, it would be 9+3+3 = 15

Answer:
The ball has hit the ground in about 1.137 seconds.
Step-by-step explanation:
The ball has hit the ground when the height between the ball and the ground is 0. So we will be setting h equal to 0 and then solving this equation for t.
h=-16t^2+vt+s
v represents the initial velocity
s represents the initial height
v is given as 5ft/s.
s is given as 15ft.
Inputting these in result in:
h=-16t^2+5t+15
Now we are finding for what t's do we have h=0:
0=-16t^2+5t+15
Let's calculate the discriminant to predict how messy are answers are going to be.
Discriminant=b^2-4ac
Discriminant=(5)^2-4(-16)(15)
Discriminant=25+960
Discriminant=985
It isn't a perfect square so we can't factor this.
I'm going to use the quadratic formula:
This implies we have two values for t to look at when h=0:
or
Inputting both of these into the calculator:
or
So the answer that makes sense here is the later answer.
The ball has hit the ground in about 1.137 seconds.
