this equation is a non linear equation
Answer:50
explanation:
30x5 is 150 and 150 plus 50 is 200 200 divided by 4 is 50
Step-by-step explanation:
<u>Solve inside the first parentheses:</u>
![2(8 + 1)(7b + 4)](https://tex.z-dn.net/?f=2%288%20%2B%201%29%287b%20%2B%204%29)
![2(9)(7b + 4)](https://tex.z-dn.net/?f=2%289%29%287b%20%2B%204%29)
<u>Multiply:</u>
![18(7b + 4)](https://tex.z-dn.net/?f=18%287b%20%2B%204%29)
<u>Multiply using Distributive Property:</u>
![126b + 72](https://tex.z-dn.net/?f=126b%20%2B%2072)
Your simplified expression is 126b + 72.
Rectangular pentagons don't exist, a shape can be either a rectangle or a pentagon but not both, so for this answer, I'm going to assume you meant "regular" =P
If you did indeed mean regular, then true, all regular pentagons are similar to each other. Regular means that the shape has all angles of equal measure and all sides of the same length. Similar shapes have the same angle measures as each other, but the side length may be variable. So basically, for similar shapes are either shrunken or magnified versions of each other.
Hope that helped =)
