Answer:

540°

Step-by-step explanation:

Given that formula to calculate sum of interior angle of a regular pentagon

<h3> s = (n-2) * 180</h3>

<em>where n is number of side of a polygon which in this case is 5 because pentagon have 5 sides</em>

s =(5-2) * 180

s =(3)* 180

s =540°

A pentagon has 5 sides, and can be made from three triangles, so you know what its interior angles add up to 3 × 180° = 540°

Hope it helps you.

Write 3x^2-18x-6 in vertex form
Vedmedyk [2.9K]
The standard form of a quadratic equation is \displaystyle{ y=ax^2+bx+c, while the vertex form is:

                      y=a(x-h)^2+k, where (h, k) is the vertex of the parabola.

What we want is to write \displaystyle{ y=3x^2-18x-6 as y=a(x-h)^2+k

First, we note that all the three terms have a factor of 3, so we factorize it and write:

\displaystyle{ y=3(x^2-6x-2).


Second, we notice that x^2-6x are the terms produced by (x-3)^2=x^2-6x+9, without the 9. So we can write:

x^2-6x=(x-3)^2-9, and substituting in \displaystyle{ y=3(x^2-6x-2) we have:

\displaystyle{ y=3(x^2-6x-2)=3[(x-3)^2-9-2]=3[(x-3)^2-11].

Finally, distributing 3 over the two terms in the brackets we have:

y=3[x-3]^2-33.


Answer: y=3(x-3)^2-33
