3 + 12 (y-4) = 40
*Use distribution*
3 + 12y - 48 = 40
*combine like terms*
-45 + 12y = 40
* what you do to one side of the equation you have to do to the other side
-45 +12y = 40
+45 +45
-----------------------
12y = 85
*now you divide to isolate variable*
85
------- = 7
12
Y =7
this one would also be the third option
Answer:
x = 7
Step-by-step explanation:
<> sum of the interior angles of the polygon is (8-2)*180 = 1080°
<> since all the lengths are equal it implies all the angles are equal
<> there are 8 angles
=> 8(16x + 23) = 1080
=> 16x + 23 = 135
=> 16x = 135 - 23
=> 16x = 112
=> x = 112/16
=> x = 7
