The critical points of a rational inequality are x = -4 and x = 2. Which set of points can be tested to find a complete solution to
the inequality?
x= -4 and x = 2
Ox= -5 and x = 3
O x=-5, x = 0, and x = 3
Ox= -4, x = 0, and x = 2

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

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,
