Step-by-step explanation:
<u>Step 1: Define Equation</u>
3.5(x + 12) = -2x + 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3.5: 3.5x + 42 = -2x + 18
- Add 2x on both sides: 5.5x + 42 = 18
- Isolate <em>x</em> term: 5.5x = -24
- Isolate <em>x</em>: x = -4.36364
The sum of interior angles in a regular octagon equals 1080 degrees.
So 1080 / 8 = 135
z = 135
8 = 4 + 2c
move 4 to the other side
the sign always changes when moving to the other side
8-4= 4-4+2c
8-4= 2c
4= 2c
divide both sides by 2 to get c by itself
4/2= 2c/2
Cross out 2 and 2 divide by 2 and then becomes 1*1*c= c
c= 4/2
Answer: c= 2
