Answer:

l= 3 and w=10+4x

l=6 and w = 5+2x

l=2 and w =15+6x

Step-by-step explanation:

The area if a rectangle is found using the formula A = l*w. This means two things multiply to make the area. Take the expression and break it down into two factors to find the possibilities.

30+12x factors into 3(10+4x) so l= 3 and w=10+4x
30+12x factors into 6(5+2x) so l=6 and w = 5+2x
30+12x factors into 2(15+6x) so l=2 and w =15+6x
30+12x factors into 1(30+12x) so l=1 and w= 30+12x

Answer:

x>-6, x<-4

Step-by-step explanation:

|x+5|>-1

x+5>−1 (Possibility 1)

x+5−5>−1−5 (Subtract 5 from both sides)

x>−6

x+5<−(−1)(Possibility 2)

x+5<1(Simplify both sides of the inequality)

x+5−5<1−5(Subtract 5 from both sides)

x<−4

x>-6 or x<-4
