Answer: A' (-4,0)
Step-by-step explanation:
The exterior angles of any convex polygon add to 360 degrees. So for a regular pentagon, the exterior angle is 360/5 = 72 degrees. The interior angle is supplementary to the exterior angle so is 180 - 72 = 108 degrees. So the sum of them is 5(108) = 540 degrees.
Answer: 540 degrees
So with more than 1 pair of parentheses, you must work from the inside and make your way outside.
Firstly, solve 6 + 4: ![10\times [10\div 2]](https://tex.z-dn.net/?f=10%5Ctimes%20%5B10%5Cdiv%202%5D)
Next, solve 10 ÷ 2: 
Lastly, solve 10 × 5, and <u>your answer will be 50.</u>
So y=12 when x=6. If x=18, y must also be multiplied by 3; and so <u>y=36 when x=18.</u>
