Which of the following best describes a regular polygon when the measure of each interior angle is 45 degrees? a) hexagon b) octagon c) triangle d) quadeilateral

The answer is B because if it equals 45 degrees then a Octagon will be the right answer. 

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
