F(x) = g(x) for x = 1 and x = 3. Verify that for yourself.
Exterior angle = 180 - 144 = 36 degrees
Number of sides = 360 / 36 = 10 sides (answer)
It most common to round to the hundredths place, this is two spaces after the decimal.
So look two spaces right - 0.17. If the third digit (in this case 6) is higher than 5 you round the number up if its not, keep it the same.
"6" is greater than five, so round it to about (or approximately) 0.18.
an equivalent expression is 5y+4
there is 3y which is y+y+y
so you have y+y+y+y+4+y
there are 5 y so it is 5y
then you have +4
5y+4
