If x is the measure of the angle , 2x is the measure of the supplement.
and x + 2x = 180 => 3x = 180° => x = 60°
Answer:
(4 + w)^7 ÷ 2
<em>good luck, i hope this helps :)</em>
Answer:
![(m + 2)^{2} - m^{2} - 12 = 4(m - 2)](https://tex.z-dn.net/?f=%28m%20%2B%202%29%5E%7B2%7D%20-%20m%5E%7B2%7D%20%20-%2012%20%3D%204%28m%20-%202%29)
Step-by-step explanation:
Step 1:
Write the expression
![(m+2)^{2} - m^{2} - 12](https://tex.z-dn.net/?f=%28m%2B2%29%5E%7B2%7D%20-%20m%5E%7B2%7D%20%20-%2012)
Step 2: Expand ![(m + 2)^{2}](https://tex.z-dn.net/?f=%28m%20%2B%202%29%5E%7B2%7D)
![(m+2)^{2} - m^{2} - 12\\(m+2)(m+2) - m^{2} - 12\\m^{2} + 2m + 2m + 4 - m^{2} - 12](https://tex.z-dn.net/?f=%28m%2B2%29%5E%7B2%7D%20-%20m%5E%7B2%7D%20-%2012%5C%5C%28m%2B2%29%28m%2B2%29%20-%20m%5E%7B2%7D%20%20-%2012%5C%5Cm%5E%7B2%7D%20%2B%202m%20%2B%202m%20%2B%204%20-%20m%5E%7B2%7D%20%20-%2012)
Step 3: Collect similar terms
![m^{2} - m^{2} + 4m + 4 - 12\\4m - 8](https://tex.z-dn.net/?f=m%5E%7B2%7D%20%20-%20m%5E%7B2%7D%20%20%2B%204m%20%2B%204%20-%2012%5C%5C4m%20-%208)
Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.
![Therefore\\4m - 8 = 4(m - 2)\\Hence,\\(m+2)^{2} - m^{2} - 12 is a multiply of 4 because the expression is equal to 4(m-2)](https://tex.z-dn.net/?f=Therefore%5C%5C4m%20-%208%20%3D%204%28m%20-%202%29%5C%5CHence%2C%5C%5C%28m%2B2%29%5E%7B2%7D%20%20-%20m%5E%7B2%7D%20-%20%2012%20is%20a%20multiply%20of%204%20because%20the%20expression%20is%20equal%20to%204%28m-2%29)
9 or 3^2 is HCF, all common factors are 1, 3, and 9 or 3^2
Not a function because it does not pass the horizontal line test. It has 2 solutions
