3, would be 9.75
4, would be 13
5, would be 16.25
6, would be 19.50
7, would be 22.75
8, would be 26
9, would be 29.25
OR 3.25x = y (y being 3-9)
73.14 $ knowing that the tax would be 4.14$, added to 69$ would be 73.14$
It is a multiplication sign. *
I hope I helped.
a)
We know that a 4-sided polygon's angles add up to 360 degrees
so to find x:
360-(69+118+84)=89 degrees
b)
For a 4-sided polygon we also know that the outside angles add up to 360 degree.
so to find p:
360-(100+62+106)=92 degrees
Hope it helps!
Question 4 is (1,2)
Question 5 is (1,0)
These are are definitely correct
