**Answer:**

**Step-by-step explanation:**

f(x) = x^2 + 3x − 4

g(x) = x + 5

To find f(x) * g(x) we multiply f(x) with g(x)

First multiply each term in f(x) and multiply with x+5

x^2 times x+5 becomes

3x times x+5 becomes

-4 times x+ 5 becomes -4x -20

so f(x) * g(x) =

Combine like terms

f(x) * g(x) =

**Answer:**

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

Answer:3

If x=0 or x=1 it is trivial, so 0<x<1. Define a=1−x2, then 0<a<1.
