Question

What is the value of x?
(2x + 4)
(3x+6)
(4x-23)
(3x-18)
(2x-3)

Answer 1

x=41

Explanation:

If this is a polygon, I'm going to assume that it has 5 sides.

s=(5-2)(180)

s=3(180)

=540

(2x+4)+(3x+6)+(4x-23)+(3x-18)+(2x-3)=540

Now simplify. Add the x's and the numbers together. Then divide.

14x-34=540

14x=540+34

14x=574

x=574/14

x=41
