For this case we have that the area of the triangle is given by:

Where:
b: It's the base
h: It's the height
We have to:

The atura will be given by:

So, the area is:

Answer:
144
Answer:
The vertex of the function is 
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:

It's vertex is the point 
In which


Where

If a<0, the vertex is a maximum point, that is, the maximum value happens at
, and it's value is
.
f(x) = x² - X + 2.
Quadratic equation with 
So



The vertex of the function is 
The answer is 12 because you got to add
21/8 miles per hour. Or 2 and 5/8 miles per hour
From the Quotient-Remainder Theorem follows that for every f(x) there exist unique polynomials q(x) and r(x) such that:

,
where r(x) is called remainder.
If r(x)=0, then f(x)=h(x)q(x) and q(x) is adivisor. If q(x) is of form q(x)=x-a, then a is a root of f(x).
