Answer:
Step-by-step explanation:
Let's look at the first two, and hopefully you'll be able to figure the rest out:
1. Answer below
The problem asks us to solve for 
, so that means we need to get on one side of the equation by itself. To do so, we will need to divide both sides of the equation by 
:
2. Answer below
The problem asks us to solve for 
, so that means we need to get on one side of the equation by itself. To do so, we will need to add 
to both sides of equation:

Answer:
Point C
Step-by-step explanation:
At point C, the graph is changing from decreasing to increasing.
Answer: 20 cm
To solve this, use the Pythagorean Theorem, a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse of the right triangle.
**The Pythagorean Theorem only works for right triangles.**
Substitute in the values.
a² + b² = c²
12² + 16² = c²
Solve for c, the hypotenuse.
12² + 16² = c²
144 + 256 = c²
400 = c²
c = √400
c = 20
