Step-by-step explanation:

First distribute the 2x to get:

4x² + 10x

Then distribute the -5 to get:

-10x - 25

Then combine

4x² + 10x - 10x - 25

The 10x's will cancel leaving you:

4x² - 25

Hey you can help me out with this

iogann1982 [59]

Answer:

Step-by-step explanation:

To find the angles of any shape with all sides equal in length, we use the formula:

$\frac{(n-2)*180}{n}$ , where n is the number of sides

For a pentagon, we get the equation:

$\frac{(5-2)*180}{5}$ $= 108 degrees$

Thus the measure of each in a pentagon if the lengths of all five sides are equal is 108 degrees.

Hope that helps!
