Hey can you me posted picture of question

For this case we have the following polynomial:
 x2 + 6x + 8
 We note that the polynomial can be rewritten as:
 (x + 4) (x + 2)
 
 A common factor binomial for this case is given by:
 (x + 4)
 option B

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
